Rogz Pop-Upz are a super-fun, easy to pick up toy for hours of endless fun! This self-righting toy will always stay upright due to the special weight in the bottom - no matter how far or high you throw! This special weight also causes erratic bouncing and wobbling for added mental stimulation and fun. The special shape is easy to pick up in both land and water. This floating toy is also easy to see in the water and easy to pick up and carry while your pet is swimming.
