OKOK, please assume that if I didn't respond to an action directly, it produced nothing of note!

Malleus burns the flowers, and they go a little. . . crazy?? At being attacked?? They will start to lash out at the group and try to take big bites out of anyone within reach! They are super weak though and can be beaten back into submission. RUDE, MALLEUS.

Rex knocks on the morgue doors as a joke, but-- something knocks back?? Mirroring his knocks precisely. If anyone else tries knocking on the door, the same echoes occur, like whatever is inside is trying to communicate with the group outside. There are no electronic panels or keys that would open the morgue doors, and Rex won't be able to pry open the doors, no matter how hard he tries. Even after Rex stops knocking, whatever is inside the locker starts pounding against the door, the sound growing louder and louder with each passing moment. Zenkichi, as the detective on the lookout for morgue locker clues, will notice a symbol suddenly light up the morgue locker door: it's the same symbol used to mark the Basilisk dorm.

And then Rex shoots the door, and it pops open with a loud BANG, and BURST OF FIERY SMOKE. A sense of death and mourning flows out of the morgue locker, along with a flailing creature who is. . . on fire. And a little berserk. The creature will attack the group instantly due to its berserked state, and it is extremely powerful! Lvl 80 compared to everyone else being lvl 20. It will not be able to be defeated by normal means, and injuries will be moderate, at the least!
