False Appearance. While the mimic remains motionless, it is indistinguishable from an ordinary bunch of balloons.
Gassy Pop. When the Balloon Mimic is reduced to 0 hit points, it pops with a loud farting noise, releasing a laughing gas from the balloons. Each creature with 15 ft. must make a DC 12 Wisdom saving throw or become affected by the gas, perceiving everything as hilariously funny and falling into fits of laughter. The target falls prone, becoming incapacitated and unable to stand up for 1 minute. At the end of each of its turns, and each time it takes damage, the target can make another Wisdom saving throw. The target has advantage on the saving throw if it's triggered by damage. On a success, the gas effect wears off.
Multiattack. The balloon mimic makes 1 Static Electricity attack and 1 Bite attack
Static Electricity. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 3 (1d4+1) lightning damage.
Bite: Melee Weapon Attack: +3 to hit, reach 5ft., one target. Hit: 4 (1d6+1) piercing damage plus 3 (1d6) lightning damage.
Flee. The Balloon Mimic instantly flees if it survives a piercing weapon attack.
