Mermaids (The Legends of Treasure Island)

The Mermaids are characters who appear in The Legends of Treasure Island TV series. They appear in episode "Tails We Win" where they befriend Jane and help her rescue her friends from Silver and his pirates.

It seems that these mermaids, unlike the Merman Prince, possess some particular and creepy characteristic: if anyone pass too much time along them, they can fall sick from a weird and dangerous disease, like it was happenning to Jane in this chapter. Jane was starting to feel ill, weak, her fur was becoming pale blue and her hair was going pitch black, just like them, which could only mean that being in direct contact with these mermaids will eventually turn you into one of them.
