ENGINEERED FOR BATH TIME FUN! Help your little builder get creative in the tub with this trio of Boon Bath Toys. Boon Pipes turn bath time into a scooping and pouring extravaganza! These five differently shaped pipes can be used individually or put together to make a chain for a flow of watery fun. Add in Boon TUBES, and there are now eight watery wonders that let your toddler discover even more ways to play. Each TUBE and PIPE interacts with water differently for plenty of ways to experiment. Boon COGS completes this set for maximum bath time fun. They spin when water is poured over them. Positioned just right, they'll run like a fine-tuned machine. These bath toys suction to the wall so the water goes back in the tub, not on the floor. With all of this to play with, the only challenge will be getting your little gear head out of the tub!
