Helloooo, I think ya should add lizards!

Different designs for biomes like the frogs, cows, pigs, wolves etc, like for dessert little dark brown with grey-brown stripes, grasslands are like common house geckos, taiga could be red with dark red stripes, snowy plains and just snow places, white with grey stripes or just don't exist unless you spawn them in, and the ones in the dappled forest should be like, yellow with orange stripes, and they should all be about the size of silverfish! (I just like lizards✨)
