Tammy is an incidental ("one-shot") character, appearing in the episode Adventures in Squirrelsitting.
Tammy is a juvenile (approximately teenage) squirrel of indeterminate species (Though most likely of the Sciurus genera). She has long red hair kept in a single braid, blue eyes, and a long volumous fluffy tail typical of tree-dwelling squirrels. Her clothes consist of a pair of blue jeans, a pink long-sleeved button-down shirt with oversize tails that are never tucked in, and a pink arch-type bow worn on her head.
Tammy is notably strong-willed and exhibits a certain naivety consistent with her depiction as a teenager. She has a simultaneous overconfidence in her own abilities and a craving for approval and acceptance from her perceived hero figure (Chip).
Episode and Role
Tammy appears in one episode, Adventures in Squirrelsitting. Tammy and her family first encounter the Rescue Rangers when they accidentally crash straight through the front door of the family's home, as a result of a mishap while attempting to retrieve the Maltese Mouse (a small artifact apparently of some value) from Fat Cat, who has stolen it. Tammy and her sister Bink are used as hostages by Fat Cat to force the Rangers to return the Maltese Mouse to him. As a result of Chip's rescue efforts, Tammy develops a romantic crush on him, complicating the situation.
After the initial hostage crisis is resolved, the Rescue Rangers are roped into babysitting Tammy and Bink overnight. During this time, feeling rebuffed in her romantic advances towards Chip, Tammy attempts to prove herself by sneaking away from Ranger headquarters with Bink, in an idealistic but ill-fated attempt to retrieve the Maltese Mouse on her own.
The Rescue Rangers attempt to enter Fat Cat's casino in disguise, but are discovered and captured. In the resultant struggle that forms the climax of the episode, Tammy and Bink end up playing a significant role in the Ranger's ultimate escape and successful recovery of the Maltese Mouse.
Accepted Fan Fiction Conventions
Non-canonical conventions concerning Tammy tend to be highly variable, tending to be dependant on the personal preferences and creativity of each individual fan fiction author. She has no notably common last name, family or personal history, or future role depiction among the Rangers.
However, in those stories where she does become a member of the team, she is often depicted as a nurse or paramedic. One of the most prominent examples of this is the fan comic Of Mice and Mayhem.
