Silverfish Mabel is a antonigist in Abandoned Discovery Island. Also in a fan game made by TheDeadBody called FNATI: The Insect Suits Wrath.
It is just a normal silverfish, but with Mabel Pines's head.
Silverfish Mabel can just start anywhere and slither everywhere else before appearing in the office. For her jumpscare, she jumps at you. You must hide under the desk quick before Silverfish Mabel comes to the office.
- Silverfish Mabel is nasty, possibly because she is a insect.
She does the same noises what silverfish make.
