I have a mighty need to make anime Wakko Warner and Fat Gum into MLP OCs, so.... here's part one! Roscoe!

Ever the foodie, he had a popular blog in the Caninia doing food reviews and supporting small businesses. When a curry shop opened in Canterlot, his extremely sensitive nose managed to pick up on the strong smells. He dug his ass all the way to the restaurant, scaring more than a few ponies on his way, and realized how much he yearned to branch out. While Caninia has its own delicious types of cuisine, Roscoe was no longer satisfied. He needed to travel.

Curry is still his favorite food currently.

Along his travels, it was hard to make friends since Equestria was still relatively xenophobic at the time, but he eventually ran into a pony / horse hybrid named Honey Tone (will be inspired by Fat Gum from My Hero Academia) and the two become fast friends. While they greatly enjoyed traveling together, they both eventually agreed that they needed a home base-- somewhere to live and come back to. They decided to try their luck in Ponyville since it had a reputation for open-mindedness due to the School of Friendship.

While settling into town, the two befriended a local beverage vendor, Blackberry Fizz, who went out of her way to push for accommodations for larger species within the town. The three eventually realize they have feelings for each other and become a happy little trio.
