Mouse Token — deltarune

Mouse Token is an unused armor item, gives +1 DF and +2 Magic and can be equipped by any party member. Just as Dealmaker, Mannequin and Frayed Bowtie give elemental defense against Element 6, this item gives elemental defense against Element 7.^[1] However, Element 7 is not currently used in any bullet, similarly to Sky Mantle's behavior.

Flavor Text

This guy's... familiar? [When equipping it to Susie]
Chu! Healing power UP! [When equipping it to Ralsei]
... from the family entertainment center? [When equipping it to Noelle]

Trivia

Due to an unused duplicate of the "mouse hole" sound effect from Undertale existing in the game files,^[2] it is possible that both of these assets are intended to be related in some way.
When given to Noelle, she assumes it is from a family entertainment center, a reference to Chuck E. Cheese.
