Now children can launch their Thomas & Friends MINIS engines across the floor and race their friends! This Launcher comes with a Percy MINIS engine. With a built-in clip on the back lever, the Launcher can be taken wherever you go! Load the MINIS engine into the Launcher, place the launcher on a flat surface and press the side button. The MINIS engine launches out down the track ramp door! For easy portability, store your MINIS engine inside the launcher by clipping inside and shutting the ramp door.
