Hello! I asked to make it to 1.21.4, and I was impressed!
I also have 2 ideas:

Can you add the penguin?
Also, make it so that you can tame a warden by feeding echo shards. On taming:

Rideable
Remove Darkness effect
Protect the owner from hostile mobs and untamed wardens.
Please cuz I've been finding one.
Fabric/Neo/Forge/Quilt.

Hi,
Faboslav will add Penguin and Barnacle in the future.
For second probably something like that won't be in the mod.

Hello there, basically what @digi2303 mentioned, mobs are planned, but i will not edit anything else non related to the mod :).
