Here is a cute and colorful baby mobile made by Tykes. It has a velcro loop on the top to attach to a carseat, crib, stroller, etc. It has a yellow elephant attached to the blue ring and a purple hippo, orange giraffe and green rhino hanging from loops on the blue ring.
The hippo rattles and the giraffe crinkles when you press on it. In good condition from a non-smoking home.
