Hello everyone!

So I recently had this idea of creating a modpack that goes with an adventure map, based on the original version of Rayman Raving Rabbids. The basic premise of the game is that Rayman (The Player) is trying to save the Glade of Dreams from the Rabbids, who look much different than how they do now. During the game, the player will be able to ride UFO's, giant eagles, spiders, and a variety of other mounts. The main goal of the game is to defeat Commander Barranco the 3rd before he gets to the Heart of the World, which will give him ultimate power.
This map may take a while to make, but please suggest anything in the meantime.

Sincerely,
