A Bionics jammer, center, designated by a star worn on her helmet, tries to sneak through a pack of Dogfightin' Dames blockers to score points. The Dogfightin' Dames took on The Bionics on March 19 at the Winnwood Skate Center in Kansas City, Mo.
With the Dogfightin' Dames yelling in support, Dee Claw (bottom) tangles with The Bionics' Poison Ivy. The two skaters had the most penalties in the first period, so they were sent to the Penalty Corner where the roll of a giant die determined the penalty to be served: a pillow fight.
Princess Anna Conda, left, the jammer for The Dogfightin' Dames, attempts to score by passing Snap Dragon, right, a blocker for The Bionics. At center, trying to push Anna Conda through, is The Dames' Dee Claw.
