Cry attracts other monsters
Gibbering Troolis is a species of monster with a call that attracts other monsters.
At an unknown point, a Gibbering Troolis was captured by the Lakewood Troop.
It is among the captive monsters which escape courtesy of a power failure.
It roams the streets of Lakewood, and sees Felix wearing a Gibbering Troolis costume. Mistaking him for a real Troolis, it falls in love with him and begins following him around until Felix lures the Troolis into the basement of Hayley's haunted house, where its cry attracts the other escaped monsters into a trap laid by Jake and Hayley.
When Felix removes his costume to reveal he is human, he retreats. Moments later, a Ratadon retreats to the basement and is trapped inside with the Troolis and Phoebe, where the two monsters are beaten up by each other and Phoebe takes bake her Halloween candy.
The two monsters were presumably recaptured moments later with the other monsters.
When the Gibbering Troolis finds a mate, it will follow it everywhere and stick its tongue in the mate's ear. It is also natural enemies with the Ratadon and Helmatrops
