You flip on your back and start doing backstroke. You are sure your going to start struggling soon : you don't know how to swim!
Then, you feel a light tingling sensation throughout your body. OMG! you think. This lake is famous! It's the Lake Of Many Swimmers, and it allows anyone to swim. You thought it was only a legend. You're so glad.
Suddenly, a thought worms into your head. If this part is true, then the other part could be too!
There is meant to be a monster lying in the depths of the lake, waiting for its unsuspecting prey. The only way to defend yourself is to stop what your doing immediately and start doing the Funky Chicken.
