Here at TT we've sold the amphibious R/C Morphibians from Kid Galaxy for years. They're fully-functional remote control vehicles with 4-wheel drive that work on land and water (that's the amphibious part, right?). Require 3 AAA batteries, not included. These come in two frequencies so two different players can use them without interfering/controlling the other vehicle (call or email us if you want two of these...our online inventory doesn't distinguish between the two frequencies). Ages 4 or 5 and up.
