A great mascot racing game for the PS1.
The storyline arrives when you start Adventure Mode, which you have to pick one character and play with him/her for the whole mode without changing... however there are 4 files and you can start a new adventure with a different character. The other modes are for extra fun, especially Battle Mode.... which is 2P+ where you get random weapons and slaughter your opponents a.k.a. friends with them XD.
I loved this game very much... but it had to go when I accidentally broke it. At least someone gave me another copy of it, which doesn't work as well and has a different CD design.
