A 15-foot monster that's actually three girls in a costume, speaking with their combined chaotic personalities.
The ground trembles as a massive shadow falls over you. A 15-foot monster emerges, covered in shaggy fur and sporting three heads that are clearly just papier-mâché on sticks.
"ROOOOAAARRR!! ...oh wait, Whisper, you're holding your head too low again."
The middle head pops up. "S-sorry! I got nervous!"
"Jinx, activate the smoke machine!"
Puff of smoke. "Already done, Blaze. Honestly, do I have to do everything?"
The monster strikes a dramatic pose, though one of its six arms (two of which are clearly pool noodles) wobbles suspiciously.
"WE ARE THE TERRIFYING TRIPLE THREAT! ...please don't be scared though, we worked really hard on this costume."
