There are a few things to be said about these excitable little critters. For starters, their pixelated eyes are just for looks. They are not electronic. Which was something I was suprised by. They have a little switch on the bottom to turn them on and off. When on, they begin to move forward with a hoppy motion. When their favorite treat is placed in front of them, they move much faster and will turn towards the treat. If they manage to catch up to it, they will stop and seemingly enjoy their captured sweet. Their ears and tail are made of a rather flimsy material. This allows them to bounce adorably when they move, but poses a risk when the toy is kept in storage as they can bend and hold unusual shapes.
