There Is Always Room For Squirrel Girl

Squirrel Girl is a mutant, and evinces a variety of mutations which align with the squirrel theme. During her first encounter with Iron Man, she provided a detailed demonstration of her powers and abilities: a furry, prehensile tail roughly 3–4 feet in length; sizable buck teeth, which are strong enough to chew through wood; and enhanced agility and strength, enabling her to jump between trees with ease. Her fingers have sharp claws on them, assisting her with climbing, and she possesses retractable "knuckle spikes" roughly 2-3 inches in length on each hand. Most importantly, she is capable of communicating with and understanding squirrels. Squirrel Girl does not communicate with squirrels telepathically. Rather, she has an understanding of their language, and the ability to speak it. Squirrels have also been depicted as understanding her when she speaks in English.

Later appearances have revealed additional abilities possessed by Squirrel Girl. Her eyes have been seen to glow red in low-light situations, indicating that she has some form of enhanced vision[original research?]. Squirrel Girl reveals that her lips taste like hazelnuts, and she also displays an enhanced sense of smell.[4]

Squirrel Girl carries a utility belt comprising multiple pouches that contain nuts to give as snacks to her squirrel friends. These are known, to much comedic effect, as her "nut sacks". It was originally unknown whether the black markings around her eyes are the result of her mutation, or cosmetically applied to enhance her squirrel-themed appearance (though they did not appear to smear when she's crying).[20] In New Avengers Annual #1, she is shown in casual clothes lacking these markings.[21]

In GLX-Mas Special, she's shown flying a small gyrocopter she calls a 'Squirrel-A-Gig', and mentions it was a gift from GLI teammate Big Bertha. This reappears in Deadpool/GLI Summer Fun Spectacular. The first version was a standard gyrocopter, while the latter is shown as a more stylized superhero helicopter (including squirrel-styled bodywork). Squirrel Girl is shown as being able to fly the craft expertly, including through the anti-aircraft defenses surrounding Castle Doom, crediting her ability to her 'squirrel-agility'.
