Flighty Fluoride Scour Rangers

The Flighty Fluoride Scour Rangers are an educational superhero team that were shown in a movie in the episode "Arthur's Tooth". They teach kids that the only way to keep The Plaque Monster from destroying Toothtown is to use toothbrush power and floss power. And teamwork.

At the end of the video, some random person stated that children start losing their teeth between ages 4 and 7, to which Arthur was embarrassed that he hadn't lost any yet.

Powers
Apart from their toothbrush and floss weapons, they also use kung-fu jumps (and screams).

Appearance
Their costumes closely resemble those of the Mighty Morphin' Power Rangers (or Super Sentai, the Japanese name for Power Rangers), plus animal features (ears sticking out of helmet, etc.) There are: a male aardvark (black ranger), a female cat (yellow ranger), a male rabbit (blue ranger), and a male dog (red ranger).
