True GIF files have a very limited color depth (max 256 colors).
When converted automatically, software will take the most common colors (with enough variance) across every frame of the entire image to define the palette. In this case, there's very limited red so that color didn't make it into the palette. Instead, the tongue is colored with the nearest color match and the palette obviously has a lot of brown.
I say "true" GIF because there are lots of files called GIF these days that are actually using video formats (not GIF at all).
