Guys I think Temmie misunderstood the assignment... They actually MADE them an outfit, like made the clothing by hand... And by clothing I mean boots. It's a tiny bit lazy but also not lazy... Lazy because it's short, but not lazy because it's animated... [Also the lazy transition to the dancing] Also that montage... Well, Temmie had to do that TWICE... [Temmie is gonna need to sleep for a whole month or something bro] TLDR: It's just Temmie's abilities [Montages, music, /\ voice changing, and detaching their own limbs] | Btw, yes, Temmie's voice changed from last time, but they're capable of changing their voice, just like how they're capable of playing music randomly [Usually only music used in animation memes], and also how like how they can detach their limbs from any joints :] And yes, they can also do montages like that, it helps speed up the process for whatever they're doing, but it makes them extra sleepy.
