Kama raised $400 last year for the Polar Plunge, an annual event that raises money for the Junior Olympics.
This year he has more than doubled that amount, a grand total of $855 dollars.
He tells us what it's like to take the plunge.
Kama Henriques said "It is like so shocking, it's so cold, its actually more like stunning."
The plunge will take place tomorrow, and Kama says he will continue to raise money up until the moment he jumps in that chilly pool.
