Grow Mermaid Clamshell

Grow your very own Mermaid!

Submerge these beautiful shells in water and then watch as they grow larger and larger, until they finally crack open to reveal your very own mermaid! Within 24 to 48 hours, the shell will crack, after 72 hours your mermaids head may peek out and she will continue to grow for the next 5 to 7 days!
