Hi. I'm currently working on Star Wars-themed Minecraft resource pack called 'Star Wars creatures'. Which Star Wars creatures should I add to the pack to replace allay, axolotl, bogged, breeze, glow squid, goat, and vex?

As the pack uses Optifine's custom entity model feature, the original shape of the mob doesn't have to match with the creature; the mob's behavior is all that matters.
