Foxglove is a bat with bright pink fur who is introduced as one of the minions of a washerwoman named Winifred, who was trying to become a witch. According to her own words, she had no friends before she met Winifred. However, during the events of the episode she was featured in, she falls in love with Dale, and joins the Rescue Rangers in their quest to stop Winifred. She becomes friends with the Rangers following Winifred's defeat.
Foxglove disappeared after her debut episode, but became so massively popular with fans that she would eventually reappear in Boom! Studios' short-lived Chip 'n Dale Rescue Rangers comic book in 2010.
Foxglove made her only appearance in the Season 2 episode, "Good Times, Bat Times". She first appears when Dale falls off the bubblegum which trapped the Rangers while watching a movie while Dale is discussing with the group to which she rescues Dale from falling. Thanking Foxglove for saving him, Dale never realized that bats could hang midair when carrying so much weight because she is an airborne animal. Noticing his weight, Foxglove and Dale fall into a garbage container. Gadget then thanks her for rescuing Dale for helping get the gum off the Ranger Wing. She then decides to look at the list Monterey is reading featuring the ingredients crossed out except for two. Being grateful of Foxglove, Dale catches up with the Rangers to continue their mission while Foxglove follows the group.
The next day, Foxglove surprises Dale again while Monterey Jack discovers Winifred causing havoc across a fair. Discovering Winifred's devious plan to complete her recipe, Foxglove plans to rescue the Rangers but Dale unintentionally offends her for calling her a useless rescuer to which Zipper tells her to come back. Monterey explains that if it weren't for Foxglove's help, the Rangers would have a serious crash.
At the museum, Foxglove brings the ingredient list to Winifred to which the washer woman tells the bat to do her task by getting the final ingredient to which Foxglove could be promoted to becoming a witch's assistant. As the Rangers discover Winifred's devious plan, Foxglove confronts her for betraying her. Confronting Winifred and her allies, Foxglove then intercepts that she will get the last ingredient for the recipe for Winifred but tells her not to cause harm to her good friends.
While trying to stop Winifred from getting the Moon rock, Foxglove tells Dale to invite her for breakfast to which Dale explains that Gadget won't let her cook to which she decides to see Dale doing a warmup routine instead. Dale tells her that the Moon rock was stuck in the bagpipes to which Foxglove offers to keep the rock as a souvenir while their conservation becomes interrupted when Winifred captures the two much to the Rangers' worry.
Planning to finish her recipe, Dale tells her to not listen to Winifred to which Foxglove explains that Winifred was the only friend she had before meeting the Rescue Rangers just as the bat tells her to keep her promise in not hurting her friend. When Dale is turned back to normal, Foxglove tells Dale to escape but the two ultimately get captured. The Rangers stop Winifred from succeeding her plan just as Dale and Foxglove free themselves while escaping from Winifred. Foxglove, with the help of Dale, ruins Winifred's plan by adding a bolt that ruins the spell, causing Winifred to be arrested for her crimes.
Having repaired the Ranger Wing, Gadget tells Chip that Foxglove is teaching Dale how to hang glide. While practicing, Dale grabs Chip via hang glider to which Foxglove warns her that the hang glider can only carry one passenger just as Foxglove feels amazed about Dale's practice in hang gliding.
