The mermaids have powerful abilities. They can control men to obey there every command. They even controlled Brady and Boomer's minds to make them leave their castle and have the mermaids stay.
Lanny and The MermaidsEdit
Lanny loved Amazonia so he stayed in the castle with the Mermaid's permission, of course. He also had Amazonia call him Lanny the King of Guppies.He also asked her to be his queen.
The mermaids tricked Brady and Boomer by telling them to take them to the castle so that they could have legs. Although, they wanted legs so that they could kick Brady and Boomer out of the castle.
