Using this Grimlock action figure is super easy. First, find a clear space to play. If you want to convert it from a robot to a T - rex, just follow the one easy step that's designed for preschoolers. To switch it back to a robot, do the reverse of that step. When playing, make sure to hold it gently so you don't break any parts. Keep it away from small children who might put it in their mouths. After playing, store it in a dry place to avoid any damage. If it gets dirty, you can use a soft, dry cloth to wipe it clean. Have fun with your heroic Grimlock figure and imagine all those exciting adventures!
