Congratulations you are now an Expert Engraver!
A groove in the wood is soft, and tiny slit creates a peek hole.
You peak through your tiny peek hole.
"Vat is in ze barrel?"
What would attract the least attention is whatever our dwarf/elf are just about to tell the official, right? So maybe we ought to sound like something sitting waiting, still to be described, rather than it risk sounding like the barrel full of flour sacks is infested with vermin...
You cover the peek hole and wait for your cue.
Bembul mumbles "hrmmmf grrmmm Shells hhrmmm"
"Zer are no schells in zis fortress..." replies the dwarf with the clipboard.
Aweme says, "It's honey. We are just bringing this fruit and honey to the stills."
You try to sound like honey.
"Ve have no time for zis. Somesing triggered ze fortress defenses and killed a dog. Cog, escort zem to ze burrows."
You are wheeled down the ramp. There is silence other than Bembul's mutterings. You wonder how tall this ramp is.
About half an hour goes by. You occupy your mind coming up with a story about a kitten who goes on cool adventures. You draw the cat on the barrel.
Bembul continues to chant about shells.
"Will you shut up about the shells mate. We are nearly to the bottom." You assume that is Cog speaking and he is one of the fortress guards.
The wheelbarrow suddenly stops moving.
Wait for him to go Berserk and then tip the barrel over and roll away down a ramp.
"I WILL HAVE SHEEELLS!"
As Bembul goes Berserk you roll right out of the wheelbarrow.
OW OW OW OW OW OW OW OW
You are stunned. A siren fills your ears.
