Toys 'N' Stuff is a presumed toy store near Springfield Town Square.
Toys 'N' Stuff is never actually seen in the TV show, but it does appear in The Simpsons: Bart vs. the Space Mutants, where it can be seen in the background of Level 1 (specifically, the middle store of the rows of buildings, just after Tool World and Mel's Novelty Shop, and before Candy Most Dandy and the pet shop). It, alongside Tool World and Mel's Novelty Shop, are the only storefronts where Bart can actually visit to purchase various items needed for completing the level/game. In particular, it sold a magnet (which isn't needed for the level itself, but rather for one of the games at the third level) and a whistle (which can be used near the Springfield Retirement Castle to get Grampa to throw extra coins at you.), each costing a coin to get. It featured an extra Spray Paint canister as well as a purple flower jar that needed to be spray painted.
