The Marysville football team might be undefeated on the field, but how will they fare in the pool?

The Tomahawk girls swim team has challenged the gridiron guys to contest that might be a little out of their element, literally. The two high school teams will face off in the Fall Aquatic Extravaganza and for a good cause.

The teams are getting together to raise money for one of their own, recent M-P graduate David Kratovil. The former football player was a regular in the aquatics class offered every semester at Marysville-Pilchuck. The former student was diagnosed with Hodgkin’s Disease on his 21st birthday and the teams want to try putting a dent in the $243,000 worth of bills that are overwhelming David and his family.

Contest events will include a dog-paddle relay, inner tube relay, belly flop contest and synchronized swim-off.

The fundraising event takes place Nov. 3 from 2:15 to 2:45 p.m. with the doors to the pool opening a half-hour early. Organizers are asking for a minimum donation of $5 per person, which can also be given in the form of gas cards, grocery certificates or food items.
