Kuma combo; huntsman to small hop?

It’s as the title follows. There’s a combo I see high ranked Kumas use (namely Brawlpro), where he goes from b-2-1, d (huntsmen stance), hop, WS 1 I think? I’ve been trying to get the huntsman to small up input, but can’t figure out how. Movelist doesn’t show anything (or I’m blind af), any help/guide will be appreciated!
