Pop this colourful egg into water and a baby dinosaur slowly hatches out. Over the next couple of days it keeps growing — a tiny, hands-off science experiment that kids check on obsessively.

• Hatches in water — first cracks usually show within 12–24 hours
• The dinosaur keeps growing for up to 72 hours in fresh water
• Shrinks back when dried, so the fun can start over
• Bright, colourful shells that look great on the shelf (ages 3+)

Sold as 1 piece. Colours and dinosaur types vary — you'll get a surprise. Not edible; adult supervision recommended.
