JA-RU Giant Dinosaur Egg Growing Toy - Magic Hatching Dino Surprise for Kids - 1 Egg Assorted

This JA-RU Giant Dinosaur Egg is a water-activated toy that hatches and grows over a few days. Drop the egg into cool water, wait 24 hours for it to begin hatching, and let it reach its full size of nearly 10 inches within 48–72 hours. Each egg contains one of four mystery dinosaur styles, making it a repeatable surprise for kids. A FunaTon sticker is included with every egg.

How does the dinosaur egg grow?

Place the egg in a bowl of water kept below 36°C (about 97°F). Do not disturb it for the first 48–72 hours. The shell will crack open as the dinosaur inside expands. After 48 hours, move the dinosaur to a larger container so it can continue growing to its maximum size. The growth process is slow enough to teach patience but fast enough to keep children engaged.

What makes this a fun surprise?

Each egg is assorted in color and style, and the dinosaur inside is a mystery until it hatches. Four cool dinosaur styles are possible, so every egg offers a unique reveal. The drama of watching the egg open and the creature grow adds a layer of excitement that regular toys can't match.
