Grow your own Mermaid with this fun toy! Just submerge the pearly-finish clam shell in water & your Mermaid will break through & grow within a day! Each shell comes in its own snap-tight plastic case, making them perfect to give as a gift or as loot bag party favours!

The colour of the shell doesn't necessarily represent the colour of the Mermaid inside.

Clam shell is 3". Mermaid can grow to be approximately 4.5"-5" x 2.5"-3" or larger, depending on how long you keep it submerged under water! Once grown to the desired size, remove from water and let it dry out on a towel for 1-2 days. If it dries out, you can re-grow it by submerging it in warm water again!


  • Put the clam shell in a container and cover completely with water (under 35 degrees Celsius).
  • The shell will slowly start to break after 8-24 hours, and the Mermaid will start to emerge! Make sure the shell is always completely submerged.
  • After the shell is broken entirely, remove the Mermaid and add new water to the container. It will grow to full size within a couple of days. Watch it grow bigger daily by placing it in a bigger container filled with water!

WARNING: Small parts, choking hazard. Not for children under 5 years. Use with parental supervision.
