Otto's Irresistible Dance

Choose one creature that you can see.
The target begins a comic dance in place.
Creatures that can't be charmed are immune.
They must use all movement to dance
without leaving their space and have
disadvantage on Dexterity saving throws
and attack rolls. Other creatures have
advantage on attack rolls against it.
As an action, a dancing creature makes
a Wisdom save to regain control of itself.
On a success, the spell ends.
