In the game
In Bart's second game, Willie was in a room, where there was a locked door and only Willie had the combination numbers to open it, but he forgot. As Bart uses professor Frink's machine, he comes in Willie's mind, and had to get past a T-rex to have the paper, where the number is writen on.
- In Willie's mind there were stuff that were usefull: a trampoline, a ladder, a rake, a dougnut.
- With the help of Milhouse's glasses, Bart could see the numbers that are written on the paper.
