Raving Rabbids: Travel in Time (also known as Rabbids Travel in Time 3D or just simply Rabbids 3D for the 3DS game) is a video game developed and published by Ubisoft for the Wii and the Nintendo 3DS.
One of the Rabbids accidentally go through time with a washing machine. The goal of the game is to play as many minigames as you can. There are 4 worlds: Prehistory, Ancient Egypt, Ancient Greece and Rome, and The Middle Ages. Each world has 16 levels as well as several bonus levels and minigames. There are two modes: Mission Mode, and Record Mode. In mission mode, you have to collect as many Coins and rubber duckys as you can and kill all the raving rabbids, and record mode is the same thing except there is a timer and you have to finish the level in record time every time you play it. In the bonus levels, there is usually a countdown and you have to finish the countdown before it gets to 0.
The game has the same worlds as the Wii version, but it is a 2D Platformer instead.
