An Epipen (a.k.a, an "Epinephrine Auto-Injector") is a tool used to inject measured doses of epinephrine. It's seen in the show to fight anaphylaxis (a severe allergic reaction).
So far, it has appeared in the episodes: "Panda's Date", and "Lucy's Brother".
Appearance[]
An EpiPen is red on the front, and there is a dark green arrow pointing at the red cone-looking top. An EpiPen is also blue on the back, but most of the color is chartreuse and white on the EpiPen.
Panda's Date[]
When Panda accidentally ate peanut-filled cookies offered by the Nut Shack, his face began to swell up as he was experiencing a severe allergic reaction. Grizzly and Ice Bear were looking for help when Lucy jumped in to save Panda with her EpiPen.
Lucy's Brother[]
When Clifford was exposed to peanut butter, he went into anaphylaxis and needed to be injected with an EpiPen. Panda was also experiencing a severe allergic reaction (Panda is also allergic to peanuts) and risked himself just to save Clifford by using the spare EpiPen from Clifford's bag.
