lumpter 

A lumpter is a strange creature found in the baglands of Scotland. It runs about with no real aim and has short stumpy legs. It has a smiley face when it is not shouting its mouth off or having a wobbly. Do not go near them as they are exceedingly dangerous. BEWARE OF THE LUMPTER

Oh my gosh did you see that lumpter right there?! It just waddled by and shat on the carpet!!
