Help with Activity

Recently my sqn has gotten groups of cadets to have a dragon den type of night - where each group presents an idea for a parade night that is run that group.

We had our first one recently and most of the group selcted wasn’t down. Me and a few other were chosen to help run and it was quite a fun night.I used my activity of the river puzzle with a sheep, fox and a cabbage/hay bale as I didn’t expect the group I was in to be picked to run the next one.

I now have a dilemma as a lot of cadet now know how the solve the puzzle and I’m afraid that it will get boring really quickly and turn into competition of who can get across the most times.

I was hoping someone could help adapt the idea to make it a little more intresting and fun the cadets.
