Built safely into the sturdy ABS plastic frame are five vibrant silicone bubbles in varying sizes and colors. It's so simple, yet oddly, so brilliantly fun, fascinating, and impossible to put down... fo babies... or adults!

Push them all the way in to pop them through to the other side. Delve into the simple delight of poking them with your fingers. It's a perfect sensory adventure babies and toddlers can take with them wherever they go!
