What you get

• Two Dino Age Megga Grow Eggs, each concealing a surprise dinosaur inside
• One FunaTon sticker for extra fun

How it works

To start the growth journey, place each egg in cool water. After about 24 hours, the egg will crack and a dino begins to swell. Leave it submerged for another 1–2 days to reach jumbo size, then transfer to a larger container if you want to continue the growth process. The result is a large, display-worthy dinosaur that adds a tactile science twist to playtime.

• Submerge in cool water to begin
• Hatch time is about 24 hours
