Ashley sees Cat's attention and looks with her truesight and blindsight as she moves closer, she gives a hand sign, holding up three fingers, silently she points South where Cat heard the sound. Based on the sound your own feet are making on this old splintered wood, whatever these are, are heavier than your group.
Ashley whispers, "Three hunched figures squat near the South end, they look like they're eating something and gnawing on bones. They have pointy ears and they're big."

Ashley looks at Yulya Incredulously.
"He'll be blown apart, do you think that hurts? I'll feel it too anyway, so whatever."

Mr. Bigglesworth runs at them with a burst of speed, but since they had initiative, realizing they've been spotted, they call out with a raspy yell of warning but are unable to escape the approaching suicide bomber. He attacks with claw as part of his normal move just before the climax.

The explosives were somewhat new, made by the Rockseekers within the season, luckily for you they hadn't lost any of their potency as a result and make for a spectacular explosion.
The ground shakes as the shockwave spreads, kicking up dust and reverberating off the walls. The sound is deafening, everyone has gained DEAFENED 3 and will be unable to hear for three rounds.

Mrs. Bigglesworth stays back awaiting further orders. Given the commotion, the third Ghoul gains initiative due to the shock of the blast on you all and Dashes North, eager to see who's been playing with explosives, he peers over the platform down at you with a wide grin on his face.
