Puzzle Popper!! In Celebration of Autism Acceptance Month, we have designed this new and engaging 4pc Puzzle Popper. In addition to helping to develop mine motor skills, improving focus, and reducing stress/anxiety, its new shape allows for endless puzzle combinations and bubble popping fun! Provides multi-sensory feedback with repetitive bubble popping sound, and tactile sensations. One low volume popping side, and one loud popping side for a diverse auditory range. Perfect anxiety reducing tool to help with sleep training, reducing screen time and increasing child engagement. Its bubble popping sound is addicting and will make you want to keep playing over and over. Once you complete one side, turn it over and REPEAT!
