Explore the depths of Minecraft’s oceans and seas with the Aquatic Expansion Addon! This addon features 10+ sea and ocean creatures that blend seamlessly into the game’s aquatic environments — from piranhas and manta rays to giant squid and orcas.

            I don't think I can... I only allow Megalodon, Livyatan, Mosasaurus, Plesiosaurus, Xiphactinus, Dunkleosteus, Stethacanthus, Ammonite, Anomalocaris and Helicoprion to be permanent in the Prehistoric Sea Creatures. (I used to be Fisch operator)

            Didn't you make the models on Blockbench? It's ok if you don't btw for Otodus Chubutensis just make a smaller Meg with stats like Mosa (If you don't believe me just search Google :D )

            And Tylosaurus is also a Mosa but diferent skin color but smaller and weaker and it has a lower health pool (If you don't believe me again just search Google :D ) but cool that you used to be Fisch operator. I noticed that fisch's Livyatan is stronger than their Megalodon so you can recode them to the same stats and Meg is bigger (again) or if you like just keep it the same.

    Ok dev, I was wondering, why you could make this add-on official? And I see some credits in there, including FoggyHollows. Listen, I do not blame you, because you made this PERFECT!! Plus, is the developers working updates already? I mean, it was popular and where did you get so many views this time?!?! I'm happy to say, you're one popular user who's been making aquatic expansion addon very good. (10/10)

      That's because I'm probably making another update recently. That's a sneak peek of the V1.2.1 Update.
