ABOMINABLE!!!

...back up today to the scene of the ruined trousers!!!!
Roxy, straight into the same thicket,
A bark, ...a yelp ....a growl and a snarl ... but then a scream!!!
OUT IT CAME!!!
THE FUGLIEST THING YO EVER DID SEE!!!!
....were it not for the amazing Roxy, I'd have been a goner.

So possibilities; the Scottish lowland Gorilla (Latin; bigarseous horribilis)
could be!
A BenHogan Bear (the bear that golfs in the woods)
could be!
the ABOMINABLE DOUGHMAN!!! (he did smell like doughnuts)
...any other suggestions would be gratefully received  :-)
