please help me with some designs for boys

ok Fabulous Face Painters, I need some help. I have an event to paint and it is for a yoga spiritual community. I am very restricted because I can't do any thing demonic, tv or movie characters. I have plenty of things for girls but for boys, I can only think of a tiger, puppy , snake and a friendly dragon.
any other ideas? Thanks in advance

Maybe something with the elements in it? Like a water splashing mask? Or Fire Mask. I have a fire mask on my board and my son LOVES it and it's one of my easier designs too hehe.

Sharks would be a good one maybe?

Oooh, how about some sports designs... a basketball, baseball, football. Maybe a yin/yang symbol for the yoga group? Boys love that one. I find they also love my spider, rocket ship, and smiley face with a tongue sticking out. Also turtles, lizard/gecko, shark...
Although, those are more cheek art so not sure if you're just doing full faces? Have fun and good luck!

looking for full faces, thanks for the ideas!

Lion? Are skulls demonic? What does demonic actually mean *LOL* ?
Tribal? T-rex? Something cool with a turtle? *G*
Edit: A shark?

skull would fall under the demonic category, tho other ideas are great, thanks Lonnie
