A game mirroring Sponge Bob and his hobby - fishing for jelly fishes
Pink balloons and ribbon, hellium (if required), fishing nets
Blow up the balloons and attach ribbon so it dangles to look like jelly fish tentacles. Hellium makes the balloons float obviously, but it works if you just have a load of balloons all over the floor. Set challenges to the YP, eg how many individuals can catch in 1 minute, or how many a team of people can catch in 1 minute, or how long it takes for a team to catch them all.
