Ok, if you came to help...
THANK YOU.
Mmkay, now, theres a part in the... um... woods, whatever the woods are called, and there is a barrel on top of a high mount. Mkay, you get up there, and Luigi's supposed to get on top and do whatever. But, the only way that he can get up is if someone is under the barrel. I've tried putting Mario on top of the barrel but it doesn't work. Please help... I've been stuck on it for DAYS.
