Kelsey Chow is a Mermaid!

Mitchel Musso has his hands full of fins — Kelsey Chow‘s to be exact in this new still from Pair of Kings.

In the upcoming episode “A Mermaid’s Tail,” While Mason (Geno Segers) is out of town, Boomer (Doc Shaw) and Brady (Musso) meet five beautiful mermaids who promise the kings that if they grant them legs, they will never leave their side. Mikayla (Chow) warns the guys that the mermaids are evil, but they don’t listen, and once the girls have their legs, they lock the kings out of their own castle.

But when Mikayla intercedes, she falls into their trap and gets turned into a mermaid. Meanwhile, Lanny (Ryan Ochoa) bonds with the mermaids over their love of pranks.

“A Mermaid’s Tail” premieres Wednesday, September 29 @ 8PM ET/PT on Disney Channel. 15+ pics inside…
