This is a list of all minor locations that have appeared or been mentioned but hold no significant nor recurring role.
Wal-Mart is a store never seen but frequently mentioned on Inanimate Insanity. It is stated to be the store that "has everything", and given how many items that the characters have purchased from it, this has basically proven to be true. Marshmallow is the most frequent buyer of Wal-Mart products (and has owned a Rewards card), followed by Paintbrush.
The store and the products it sells can be used as a deus ex machina for the contestants. (A deus ex machina being whereby a seemingly unsolvable problem is suddenly and abruptly solved with the contrived and unexpected intervention of some new event, character, ability, or object.) So far, a remote that activates a launchpad that came with a free cucumber, a time machine, a dummy resembling MePhone4, a big shiny aluminum tree, and a boat have been bought from Wal-Mart.
The Perilous Forest
The Perilous Forest is a location shown in Rain on Your Charade, and Mazed and Confused, Taco is hinted to live, or at least go there. Microphone wrote in her diary on one of the tree stumps, where she threw her diary into the bush. Taco then got the diary, and read it. Then Microphone heard her read the diary, causing Taco to jump out from the bushes and exclaim that she wants to help Microphone. Microphone then screamed loud, and Taco turned Microphone off, saying that she "has no intention of going deaf today".
