SMG4 and Mario face off once again for War of the Fat Italians (WOTFI), but this time, there is more than their reputation on the line. Their channels are at stake as well.
Mario, SMG4, and Toad are back again for a trip. This time they go by train to visit Uniderpal Studios. However, there is a certain maniac with an overly inflated ego named Bob who wants to join them.
Oh yeah. It's Luigi time. And Mario and SMG4 are stuck right in the middle of an army of Weegee dolls that turn people into more Weegee dolls when touched. It's up to them figure out what is going on and put a stop to whatever it may be.
