Err, couldn't it be one of thouse sour with "small explosive pops" candy thingies? You know those that you put in the mouth and it start crackling in your mouth? I think I recall a few old stories on which if yukkuris ate that, nothing good came from it, or for some odd reason the "crackles" becomes explosions strong enough to pop their parts away (like in the end when the eyes and anyaru paste comes out.)
So it was a Super Spice Ball, quite the explosive effect if you ask me. Unless the reason for the "explosive effect" is them trying to throw up hard and the tape preventing it, leading to the "vomit" to come out from other holes, incluiding the eyes.
Super spicy ball(something like that) Habanero powder.Chef : cooking misterThere it is.
