Rescue Riley is a whimsical firetruck that rocks back and forth, his headlights illuminate, and his mouth moves while he sings "Wheels on the Firetruck" (variation of "Wheels on the Bus"). Rescue Riley has been adapted for use with a single, standard 3.5 mm switch (sold separately). Press and release the switch or push his button directly to activate him. Measures approximately 8" long. Requires 3 AA batteries, included.
