Pilflip

"Odd creature that adapts to changing situations by flipping over and using the limbs on the other side of its body. Adaptability is an important survival skill. If a problem seems insurmountable, try approaching it from a different angle."

Pilflips are enemies in Hollow Knight. They have antenna-like appendages on their back which function as limbs when they are flipped over.

Behaviour and Tactics
Patrols its territory without regard to the Knight. Upon being hit, it flips onto its back, changes direction, and begins to chase the Knight while hopping. Upon hitting it again, it changes direction and reverts back to patrolling.

If left off-screen for long enough, it reverts back to crawling.

Location
They are only found in the central part of the Royal Waterways.

Trivia
