Dull Bones Negative HP Overflow

[DualFelines]

(Master Quest Jr.) When using Spin Smash in a battle with a dull bones in Dry Dry Ruins, the damage from being hit by the Pokey struck in the front affects the Dull Bones, but does not cause it to collapse and it remains standing at zero HP. Repeating this causes it to remain standing with a negative HP overflow, giving it 255 HP.
