Original Description:

For one of the suddenly invented arts, a shower of Wonderbolts was needed. It is here that the flying athletes put themselves and each other in order after the show and training.
I tried to create an authentic design plus a few cool elements like a mirror. In theory, instead of watering cans, a small cloud should hang over each booth, from which water pours on pegasus.
And also in the series it was clearly shown that they have locker rooms in common for both sexes, so the same situation is with showers.
