We played the Bananarama games for our youth and they worked out great- we got a lot of positive feedback- the kids went nuts!
A couple things we did different was we had a few leaders in a car go out and give each team a challenge. If the team completed the challenge, they kept all their bananas. If they did not, they lost three bananas.
There’s a lot of banana-related challenges to be thought up, so I’ll leave it to you.
Also, before hand we told the youth not to be too abusive to their bananas, which allowed us to have banana splits after the game. (and after washing them of course).
