Most Robo Fish are made of plastic, and some Robo Shark models specifically list ABS (Acrylonitrile Butadiene Styrene) as the material.
They use water-activated technology to start swimming. Product descriptions state the toys can move in up to five directions and are capable of diving as deep as 6 feet.
Dimensions vary: small fish are about 2.76–2.8 inches tall, while playset items can be around 11.22 inches tall. Weights range roughly from 0.11 pounds up to about 1.42 pounds.
Some Robo Fish feature water-activated color-change scales that change when submerged in water and can be rubbed back to their original color after removal.
Product details consistently list the suggested age as 3 years and up for both the Robo Fish and Robo Shark listings.
Product descriptions cite use in a fishbowl or similar small water container and also reference bath time, pool play, or backyard water games.
