You and your little one can discover 8 adorable sounds when you play with the T-Rex and 15 big building blocks. Start by turning the T-Rex on with the on/off switch. Then, your toddler can get to building when they stack blocks directly on the T-Rex's head to hear cute sounds, or push it to hear more adorable sounds as it rolls. An additional 8th sound will play when the T-Rex is left idle. When playtime is over, the blocks can be stored inside the T-Rex for easy cleanup.
