Toy boxes are an object in the Mario vs. Donkey Kong series. They first appear in Mario vs. Donkey Kong.
In Mario vs. Donkey Kong series
Mario vs. Donkey Kong
There is a toy box in every Mini-Mario level. When starting a Mini-Mario level, there is a short scene in which two Toads are seen carrying a toy box, which they both throw into the air, and the toy box drops somewhere in the level.
The object of a Mini-Mario level is for Mario to guide all of the Mini-Marios into the toy box. Whenever a Mini-Mario approaches the toy box, it opens automatically. Once every Mini-Mario has entered the toy box, Mario has to close and lock it by jumping onto the toy box, then the player must press 
for Mario to perform an animation in which he says, "Haha! Gotcha!" before landing back onto the ground, then the level ends.
Mario vs. Donkey Kong: Mini-Land Mayhem!
Toy boxes are featured in the minigame levels. In odd-numbered attractions, dropping any type of Mini into a toy box with a star on it rewards point, the number depending on the multiplier below the toy box, whilst dropping Minis into a black toy box depicting a red "X" subtracts points, the number also depending on the multiplier below the toy box. In even-numbered attractions, toy boxes instead depict a Mini's face. Here, dropping a Mini of a certain character into its corresponding toy box is worth 100 points, but dropping a Mini into the incorrect toy box neither provides nor subtracts points.
