SUCTION CUP BATH TOYS
To the wall, that is. These tiny jellyfish will never sting—but they will use their suction cup tentacles to stick to all sorts of stuff including the aforementioned wall, the tub and even each other so they can be formed into cool shapes and structures.
Wash thoroughly before initial use and periodically. Hand wash in warm, soapy water. Rinse with clear water and air dry.
