Help with team names??

my schools field day is coming up and my homeroom's (cl tht is my team) teachers name starts with "K" so it has to be something with the first letter k. last year thay we the K****** not gunna say the name) knock outs. so i need something. rember its school so it cnt be inappropriate. it can be a name of an animal but not something lik a kitty or kangaroo.
