Incorrect sounds in Mu Lung Dojo

why did this happen to every low boss you'd have to fight for days on end for the black belt?

Honestly I'd skip to the save point after Lord Pirate, there's a set of 5 easy ones (relatively - I think it's Nine-Tailed Fox, Tae Roon, the Poison Golem, King Sage Cat, Jr. Balrog).

Then Elliza, Frankenroid, something, Kimera, Snowman, Blue Mushmom, Crimson Balrog... which are not as easy but I still do them.
