Donut's telekinetic shoving spell, used to push targets off ledges without revealing the caster.
Princess Donut used Astral Paw to shove Elmer from behind as he leaned out past the town limits to take Carl's gold, sending the Ursine mayor tumbling twenty feet down the slope toward the river. It is the opening beat of the party's Yankee Doodle maneuver.
Notably, the Funeral Bells guards' dots stayed white afterward — either they didn't realize Donut had cast the spell that pushed him, or they didn't care because she'd technically been outside town limits at the time. The town's Town Rules forbid magic on the streets, which is part of why Carl deliberately backed the party onto the covered bridge before calling the move.
The push that kills the mayor and hands Donut the settlement.
