Right now I have a level 51 Hyacinth Macaw, a level 50 Mochi Mouse, level 40 smth Bacon Pig, and a Raiju that's almost level 50.
I will showcase the pets in this exact post once they're all mutated.
I might also place my giant Golden Goose level 1 and see what I get out of that.
Bear this in mind, I'm pretty new to the game. Only 3 months of playing it does not mean I understand it entirely.
