Items You can Get
I dont have a photo for these, But basicalky heres a list of the items u can get with the mystery item box.
Banana Peel: Self explanatory, throw onto the track, make yeeps spin outta control
Engine Fuel: Gives the yeeps kart a lil speed boost!
Ticking Bomb: When pulled out, itll start to tick for about 5 secs before it explodes, throw it onto ghe track to send a yeep flying!
Flying Saucer: Acts like a koopa shell, when thrown, will bounce around till it hits a players kart.
Gust of wind: Sends ur kart up into yhe air, allowing u to jump over yeeps!
And before u ask why would they add wholly new items when there are already some that do the same thing? There is a very simple explanation for that. I imagine that when someone puts a go kart on, they cannot move around with their arms, they can only use it to control the kart and grab out items.
