Let them play in the dirt, then put them in the bath and toss in Scrubble. They"ll think it"s fun. Kids can fill each bulb with water, squeeze it out or slide it all around like a soapy loofa. And we gave this squirt toy two halves that unscrew. That means you can mix and match the colors. Bath toys encourage scrubbing in the tub. Interchangeable scrub bulbs. Fun textured surfaces. Fill the bulb with water and squirt it out. Unscrew for easy cleaning. BpA-free, Phthalate-free and PVC-free
