The party dubiously walked along the new corridor, and sure enough at the end was a Trolin.
"Ooh err," it said, rising from a screamer slice suofflette it had made itself, "I didn't think you lot were going to ope nthe portcullis for a while yet - I'm barely done eating. Wait, what are you doing here anyway?"
The party looked around, seeing the corridor led to a nice little kitchen/living room batchelor pad for the Trolin.
"We couldn't get the portcullis open, so even though we known Stamm has the right answer, we went this way instead," said the party in unison.
"Oh, thank goodness ...well, evilness...for that! Lord Chaos would have had my club in a blender for npot guarding the portcullis!"
"Actually, we think we are here to rescue Chaos" said the party in unison.
"Oh, well in that case there isn't a moment to lose!" said the Trolin decisively. He kneed Stamm in the groin, splatted Azizi with a screamer souflette, and lifted Gothmog's robe up so the mage ran away screaming.
"Free!" said the Trolin, running away down the corrdior and obviously away towards the entrance.
"I think...I can see a short cut around the portcullis," said Stamm with tears in his eyes on the floor noticing a small corridor.
See, you were right to take this way gentle reader, so much less effort to take this corridor and go around the portcullis. Well, except for Stamm's groin, but then you obviously hate Stamm or you would have used his correct idea in the first place!
