I'm not sure, but maybe if you get the 2.25 inch high Nintendo Red Mushroom Keychain your car will grow to immense size and you will be able to go crush some minions of Koopa! Lay the smack down on Birdo. Give the Shy-Guys a reason to be shy. Set the Chain-Chomps free! See? Just by having the Nintendo Red Mushroom Keychain your day will become infinitely more interesting. Well, I really can't promise that but people will still respect your soft rubber Nintendo Red Mushroom Keychain. Plus it'll give you more of a reason to make Nintendo based sound effects.
