|I forgot when I drew this|
1. Clarabelle and Horace have been paired in almost all their appearance in the old shorts.
2. I don't like the need to shoehorn in a love interest for Goofy just because Mickey and Donald have one.
These two shorts in particular feature Horace heavily, Camping Out especially where he was pretty much the main character:
Admittedly, he was a boring character, but I got a soft spot for him. Someone who the world used to know as one of Mickey's pals but Mickey would later become an American icon and Horace would become... well, forgotten.
