Hoi Elephant3,
Sorry to tell you that your map have been rejected.
The theme is, like kroro said before, not really original because one elephant map got added recently, and animal maps are not original in general. The build could be better, the elephants are cute, but I will prefer one main build and not multiple scattered build like you did, because it's pretty messy. The parkour is good, it's varied and fun, I'm just a bit scared about the moving minecart, but it's not a big problem. (Oh and you can skip the last slime)
Thanks for submitting your map, would be really good to see more maps from you !
