Sprocket's obsessed with pirates, so they'd at least have one interest that they'd share. I think Timber's hyperactive personality would be really fun to play out, Sprocket's a little more mellow but still can get excited over things easily if somepony else is! He'd also love to be an explorer as well, so maybe they can bond over that? I dunno, my brain's pretty dead |D
The Fun Has Been Doubled! is a My Little Pony: Friendship is Magic moderate-to-advanced forum roleplay. Set after the events of the fifth season, we currently have no overarching plot. Instead, we simply have created the world of Equestria for you as a giant playground to have fun in and to explore the magic of friendship. Canon characters and original characters are available for you to play as, both ponies and non-pony species alike! Just remember that we are account-per-character and we'll be fine!
So why don't you stay for a while, look around, and let us know if we should get a welcome party started for you.
