Still says invite invalid

The link doesn't work :/

I got the last one and i got it by buying everything in the store

I've been watching some 3DS speedruns of Garfield kart and i noticed the 3DS version of the game has more glitch shortcuts and the drifting in the 3DS version seems allot easier since you can start a drift at the very start of the race. So i am requesting another category for speedruns of the 3DS version of the game.

Oh ok thanks

Also the other 3 spoilers.

I tried it on PC and it didn't work :/

The multiplayer is out bois

I now have 4 stars by getting the platinum medals in every time trial map.

How do you get the last 2 stars?
