No You Got Jump-scared By An Inanimate Parade Float Duck - Tumblr Posts

This is your goal:

Something you could come across in a weird kitschy museum that’ll make you ask ‘what were they thinking’ and not ‘why did the curator put this here?’

I think the biggest thing mascot horror things need to get a grip on is the reasonable balance of cute/creepy. The mascot in question needs to be cute enough to realistically be for children but scary enough to actually make for effective horror. Most games always lean too far in either direction and idk maybe it's just me but immersion with these kinds of games are important for me to actually find enjoyment in them.
