So, this is the game I (Guy) and my friend Maria play after we're good and excited by having an hour of Energizers (toddler gym) and a snack to boost blood sugar levels.
You start by each standing on one of the drains in the ladies showers.
Then run towards each other, laughing hysterically, find the other drain and jump on that one.
Anyone not standing on a drain can then be chased.
And run off, giggling, and hide behind the shower curtain!
What makes this game particularly fun, is that the showers are operated by a movement sensor which is above our heads, but means that if either of the mummy's come in after us, they get wet. Which makes us laugh even more!
