Undertale Blockynovella brings Undertale characters and an original story to Minecraft, letting you interact with monsters, face bosses, and make choices that matter.

About the Add-on

Undertale Blockynovella not only brings your beloved characters from Undertale, but also adds an original story which explains why they're in the beautiful cubic world of Minecraft.

Taking place in 202X, the humans and monsters finally live in harmony thanks to a human child! But not all humans are fond of that harmony as half of them are ready to use their axes, bows, and sorcery not only to take down the humans that live with the monsters, but to try bringing them back to the underground where they think they belong.

UNDERTALE-Style Actions

You can SPARE and FIGHT your way out! Maybe your choices matter?

We shall see...

Undyne The Spear of JUSTICE (info)

Undyne The Spear of JUSTICE

Undyne is the leader of the newly formed Royal Guard, aiming to protect the villages from the illagers and the undead.

Not only does she have her spear magic, but she now has a trident as well! She got it from a Drowned that tried dragging her down when she was sitting beside a lake. She uses it a lot in combat, and since it has the loyalty enchantment, she also uses it to grab her enemies from afar! She grabbed things from afar with it too when feeling lazy but she rarely does that now since it caused a lot of destruction back then (and that said destruction was breaking Sans' new chair which was just a brick that he sits on).

Undyne's Stats

  • Health: 500
  • Attack: 10
  • Defense: 2

- Chance of spawning: Rare

- Where she spawns: Spruce Forest and near Sculk Cave (she visits there to feel nostalgic because Sculk Caves looks like Waterfall)

- Can only spawn once; if you spare her she'll be back

Note: You can't be-friends with them yet; we will add this feature soon.

Hunting Phase

"HEY, YOU, RIGHT THERE!"

Blocky armored monster with glowing eyes

This is her phase when she's first spawned. She has Warden-like hearing and will attack zombies, illagers, and players that she hears and spots.

She is invulnerable in this phase. Illagers and zombies will try to take her down with anything they have just to ultimately fail. She is also after you for a reason...

Your only option is to HIDE and RUN. You can hide behind walls or in the tallgrass, and be quiet.

There is another option however, if you are brave enough...

To beat her you have to make her miss when she throws her Trident. After that you will see that little sword icon on top of her; when you see it ATTACK HER AS FAST AS YOU CAN. You have to hit her 10 times until she reaches her BOSS FIGHT PHASE. No need to worry about damage, just hit her 10 times.

Hunting Phase Abilities

  • Spear Attack: Spears spawn in the air and aim at you. You can dodge them. When hit, it will cast Raining Spears, which are hard to avoid but possible.
  • Spear Floor Attack: Spears spawn on the floor. The attack is not too hard to avoid, so have fast reaction time.
  • Trident Throw Attack: She has a Trident with Loyalty enchantment. Instead of her trident going back after she throws it, the trident will instead be stuck on you and she drags you.
  • Super Leap Attack: She'll jump really high and aim at you like a homing missile.

BOSS FIGHT PHASE

"Show me what an ancient builder can do!"

This fight has a mix of turn-based bullet hell and Minecraft combat style, making the fight more interesting.

How Do I Beat Her?

Figure it out yourself, spoiling it here will break the surprise, so I won't! All I can say is watch out and get ready to face danger head on.

Parry Ability

Don't get too cocky, because once she parries your melee attack you will be hurt really bad.

Yeah that's it... I just wanna warn you about the PARRY ability because it's very punishable when you're too impatient; telling you all of her attacks right now would ruin the fun fighting her so... ANYWAYS

To SPARE her... Keep running and lure her to hot biomes like Desert and Savannah, you can go to The Nether also; after she passed out from dehydration give her water (any kind of water item). Note: Do this while fighting her Boss fight phase, but you can do this with her HUNTING phase to lose track from her (it won't count as a spare tho).

sans the skeleton (info)

sans the skeleton

you already know who he is.

Sans' Stats

  • Health: 1? Who knows
  • Attack: 1
  • Defense: 1

- Chance of spawning: Uncommon (same spawn chance as Wandering Trader)

- Where he spawns: Everywhere in the overworld

- Can only spawn once, but still he's everywhere

Note: You can't be-friends with them yet; we will add this feature soon.

How to SPARE Sans? You can't normally spare him but he'll dip out after the fight

(NOTE: Sans is not fully done yet so expect some changes to his assets and mob behavior)

ANYWAYS
When fighting, it's not really serious because there's no point for him, so instead you'll have a spar with him.

Hitting him 3 times will activate the fight.

There will be a Phase 2 fight soon. He doesn't have much yet; he is still Work In Progress.

Why do Illagers Attack the Undertale Monsters? (LORE)

Why Do the Illagers Attack the Undertale Monsters?

In the add-on's lore, illagers are the descendants of the human sorcerers that sealed the monsters in Mt. Ebott. Some illagers are just villagers that hate monsterkind in general.

The ashes of the monsters they've brutally killed are seeping through their skin, which explains the gray hue. Though it is a reminder of the horrible sins they have committed, they wear it proudly.

HIGHLIGHTED OUTLINE (please read when you fight the mobs)

OUTLINE

The Outline feature helps you fight against foes: it shows when you should interact or not.

NO OUTLINE

Nothing special: they can be damaged, so you can attack them (only enemies or monsters that are hostile towards players).

Preview:

Pixel art monster character sprite

WHITE OUTLINE

This means they have invincible frames; the mob will not be damaged by attacks.

Tip: When the white outline appears you shouldn't attack them because it could be a parry or they won't be damaged at all.

Preview:

Pixel art monster character sprite

YELLOW OUTLINE

This highlighted outline means they can be spared, just like in Undertale when their name is highlighted yellow.

(Note: This feature is not fully added in this PATCH UPDATE; it will be added in later updates.)

Preview:

LUST FOR DUST (Lunatic Mode)

LUST FOR DUST mode

Do an INSANE challenge like a Lunatic? INTRODUCING LUST FOR DUST MODE

This makes all the Bosses and Enemies have impossible attacks (average Sans fangames lol) so you're up for a challenge?

Use this command in chat to turn on the mode: /function lust_for_dust

To turn it off: /function lust_for_dust_off

When turned on, enemies will be highlighted red.

Preview:

Pixelated gray monster with red outline

NOTE: This stuff is not canon to the main lore of the add-on, but a neat little challenge for crazy people out there LOL

Note When Sharing This Add-on

Only share this add-on on this website. Sharing a direct link and claiming it's yours is very disrespectful. Me and the team have worked so hard on this add-on so I appreciate you have some respect for us. If you don't follow this, there might be a chance that I'll lose motivation and won't continue on this project.

So please give us some support and we will keep uploading more banger contents! :D

Known Bugs

  • Soft locking issues with the Undyne fight
  • Issues when leaving and rejoining a world mid-Undyne fight
  • Sans does not have the comic sans font

Mob Battle

For mob battle enjoyers out there, use the spawn commands or spawn them manually to enjoy the show.

Never mind — you don't have to do certain commands; just spawn them and enjoy the show.

There are some debug options in creative mode to skip the boss phases to make things easier.

NOTE FOR MOBILE USERS:

I DO NOT RECOMMEND using joystick controls on this add-on because there are some mechanics that will make the movement weird.

Thx for reading :]
