I created the model, texture and the animated glow based on a concept from Mattel for the Glow Squid. This mob was designed by the Minecraft Earth team and Mattel, and is a glowy variant of the vanilla squid. We decided later in its development to add an animated alpha map so the glowy spots would blink. Thanks to Jasper Boerstra https://www.artstation.com/jappa for pixel feedback.
I created the model, texture and animated fish for the Tropical Slime based on a concept from Mattel. This mob was also designed by the MCE team and Mattel and is a watery fishy version of the traditional Minecraft slime. This mob was also revisited later in its development to add swimming fish in its inner cube.
