Start spinning the RUBIK'S HYPERCUBE till you enter MONTAGE MODE. Find an alternate universe where the sandwich poison was sandwich poison antidote!
if that doesn't work, EMERGENCY SURGERY!
on a side not, we totally need to slot that cyborg eye into the butcher knifes materia slot. it would totally make something awesome.
Pad-bro, being a teddy hippo is immune to normal poison. only susceptible to teddy poison, and gwate big hugs.
then spits the sandwich pieces out at high velocity into the mouth of MP who swallows them.
Mike R's right: Use CYBORG EYE with BUTCH'R. If it makes something vaguely scientific rather than magical, Cad can make it Alan's problem when he zworps in sometime.
Since it's been 10 turns since the last zombie interlude, if Cad is due to see them soon, ask QUEEN for PEANUT PRODUCTS from KITCHEN. Y'know, just in case Cad has to cast SMNSNDWM (summon sandworm-- no idea how to otherwise squeeze that onto eight knuckles) sometime soon.
Ask QUEEN for FENIX DOWN, too. Or ask Pad-bro what his stuffing is made of. Without any imputation of cowardice, of course.
It'll be good when Cad finds Rhys, or vice versa: Rhys has the rubber stopper for Cad's empty sandwich poison bottle.
