CROSS BREEDING-NESS

A while ago, people found an unknown creature in the trees of Killeagh, Co.Cork.
It was presumed a squirrel until more news came out of a young boy's chimpmunk being lost a month ago.
Scientists came over and discovered the squirrel-like creature was offspring of a red squirrel and the chimpmunk. The creature was named: Southern Irish, cross-breeded, Chimpmunk Riticulated Red Squirrel.
Or Brown Squirrel for short. I made a cartoon:

Unfortunately, scientists classified this creature as vermin, and it was killed and the chimpmunk has'nt been found yet. Well, I guess that's it.
WAIT, let's spam the internet with two words: SAVE FLUBBERGASTIC!
I named the cross-bred creature Flubbergastic
