It is a creature cut from MO or intended for Hand of Odd, a huge, flying beetle-like creature. You may have seen their larvae, the mudokons feed them on plants and they grow into meetle, but industrialists feed the babies meat and they become mugs, can't find a picture of them, however. Mugs are vicious, much more so than meetles. The Art book has an older iteration of meetles, much meaner and completely different.
