A fire hydrant is an object found within the streets. When the Silly Meter is past phase one of its progression status, fire hydrants spring to life and offer Toons a power-up in damage for Squirt gags when interacting in a Cog battle nearby. Fire hydrants look different on every playground.
- During the Great Silly Particle Search, Doctor Surlee inspected a certain fire hydrant on Silly Street in which it would slowly become animated as Toons continued to collect more and more Silly Particles. According to reports from Toons, this fire hydrant was the only one that been spotted making attempts at springing to life.
