traitor item I saw in a dream: bio-cascade bomb

[Lady Birb]

6tc probably. Big item you drag behind yourself like a portapuke. Clickdrag people to shove them into it like a clown car. After you shove the first person inside, it starts a 3-minute timer, with every person after that extending the timer by 30 seconds. When the timer hits 0 it explodes, with the explosion being larger the more people are shoved inside. Can be prevented from detonating by smashing it with blunt objects until it breaks open.
