What kind of activities would you like to see when attending a mermeet?
Not strictly business/course related, also just for getting together with other mers to have fun.

So far I've come up with:

-tail races
-underwater parkour (swimming through hoops, around obstacles, etc)
-underwater trick and dance numbers
-synchro routines (with music)
-deep diving, getting objects from the bottom (in a diving pit or a lake)
-practicing mer/diver sign language underwater

ball games at the surface (while in a tail) seem also to be popular, though it's kinda not my thing lol.

Any more ideas?
(I know this was discussed somewhere sometime, but I couldn't find it.)
