They're bubbly and extremelly energetic- they go on and on talking when they least notice, spinning and and running around! They just wanna make others happy, even if its for a tiny moment-- though it'd be easier if they kept their winding key in place! and winded, ideally. When they come back from being unwided for long, they're so happy that they might celebrate with a bullet pattern play session!! be careful
When they start losing their wind up you can hear a music box go slower and creepier until their movements become almost unnoticeable, coming to a sudden stop. Their eyes become faint until they're just hollow husks within a ceramic head covered in velvety fabric. The rest of their body is stuffed, and sometimes they take some out of their pockets or eyes while searching for anything they might have storaged inside themselves
They love jokes. Specially puns. I swear this is not a sans-reference im just a giggly bad pun-lover myself, the worse, the better.
Lutka lives past the river that's visible from the bridge in which papyrus' ambushes you (and which is never crossed in-game) The whole area is circus-themed! and full of other circus-like monsters just like them
Their bullet patterns feature bubbles, clams and sea-themed merry-go-round elements, though I still have not decided how they DO attack exactly.
Nobody really knows why their horn features the deltarune. Not even themselves. If asked, they will simply answer they "don't seem to be able to remember"
