All Lost Fleas in Silksong
Fleas do not count towards 100 % completion, but the Pale Oil is necessary for 100 % completion.
Check the boxes below as you find each Lost Flea across Pharloom.
After getting Wish: Ecstasy of the End, find the Fleas in Putrified Ducts and complete the Flea Festival mini-games in Fleatopia to get the Pale Oil from Mooshka.
