Animated banana

Antimagic susceptibility. The banana is incapacitated while in an antimagic field. If targeted by dispel magic, the banana must succeed a constitution saving throw or fall unconscious for 1 minute.

False appearance. When the banana remains motionless, they are indistinguishable from a normal banana.

Slapstick. When the banana dies, any creature that moves into the space of the corpse must succeed a DC 10 dexterity saving throw. On a failure, they fall prone and take 1 bludgeoning damage. This does not take effect if the banana dies from fire or acid damage.

 Slam. Melee weapon attack: +2 to hit, reach 5ft., one target. Hit: 1 bludgeoning damage.
