Undead Mouse is an antagonist in Abandoned : Discovery Island V2
Undead Mouse randomly appears in the Office, and attacks the player.
Undead Mouse's appearance is that of Blood Mouse, except extremely withered.
Undead Mouse's behavior is similar to Golden Freddy in FNaF, he sometimes very rarely appears in the Office on Night 1, and kills the player. There is no way to get rid of him.
- Undead Mouse is Blood Mouse, which is confusing because ADI V2 is before ADI V1, and Blood Mouse is in V1
- He looks like Withered Photo Negative Mickey, but he is recolored.
