My CP's team 3 years in a row did a Holiday bonding party. Both years the gifts were socks, because all of the kids love the crazy socks. The first year and last year were secret Santa types where each girl drew a name from a bucket. That worked out really well because they were able to customize the socks they bought to fit the other girl's interests. The second year, we did a white elephant which resulted in lots of tears. I don't think the youth/mini age kids should do a white elephant because someone is going to swipe the socks they got and tears ensue because they really liked those socks.
Another bonding idea is bowling. Depending on how many stunt groups you have, you could assign 1 group per lane and make it a contest between stunt groups.
They just had color day Monday. Each elite stunt group chose a color and wore that color shirt with black shorts.
