dinosaur mask moving jaw

The mask has an internal water reservoir you fill. Opening the jaw activates a water blast that can shoot out about 5 feet.

Power varies by model: some masks require no batteries, while others need three AAA alkaline batteries to run the lights and sound effects.

The masks are described as plastic. Overall dimensions vary by model — examples listed include 4 in (H) x 5 in (W), 4 in (H) x 4.6 in (W), and one model can measure more than 13 inches wide when its frill is fully extended.

Most masks fasten with an adjustable strap at the back for a snug, secure fit. Listings provide fit guidance — for example, one notes a maximum head size of 13 inches — but exact fit may vary by model.

Listings commonly include eye openings for visibility; at least one description also notes both eye and mouth openings to improve wearability and airflow.

Some masks offer three escalating aggression levels for lights and growls. These light and sound levels are activated by opening the jaw wider, producing progressively stronger effects.

Recommended ages vary by model; listed suggestions include 4 years and up, 5 years and up, and in one description, 6 years and older.
