My daughter loves these bath toys. She doesn't link them together, as they don't stay attached at all, but she loves to float them around and fill them with water and watch the water run out of the small hole in the bottom of each one. Mama is happy because there is no place for water to get trapped, so no way for that gross black mold to form, like other floatie bath toys! I deducted one star, only because they don't link together and stay that way. Other than that, they are great.
