Trixie turned to Professor Truebridge and nodded. She could let it out. Greeeeat. Wait how was she meant to do this? Magically or Physically? She was so not going anywhere closer to that cage. I mean look at the intimidating thing. But she promised to help out and the splashing was highly amusing.

So she stood slightly closer to the cage, pointing her wand directly at the exit and said "Alohomora" as the cage swung open to let the Kappa roam free.

MEEP!

KAPPA WAS FREE!!

The Impervius charm. Could have told her that earlier. "Nah Professor. I don't mind getting wet" she giggled. Fell in the Lake enough times. And she lived in Wales, it was always wet there. Besides Kappa looked like it was having fun splashing around which gave Trix amusement as she too got wet.

"I hope that is better for you Kappa" she smiled politely. Hopefully she'd be in it's good books now that she had set it free.
