"I thought we all volunteered to come with Kang and help get rid of the Iron Worm. My understanding was we could stay here and our basic needs, a room, water, food would be catered for.
We have enough weapons between us and if you need a sacrificial lamb, I will do it. I am not of the fighter class, so once it appears you can all stab it with the javelins and swords you have got."
My simple plan to lure the creature would be to make noise near the water, drawing it to my location and then hoping you guys can trap it before it strikes.
Yuka, Yuti, I am the bait, I will summon the creature and my friends will kill it. Do you have in your camp any skin drums?" she tries to get an idea of what percussion instruments she can make music with. Skin drums are best, she has bone drumsticks (used to keep her hair in a fashionable bun), but if they don't have then empty amphora or jugs. I could partly fill some like glass bottles to create different notes. Even different sized wooden buckets will tap a rhythm.
(Learned in my family kitchen using pots, pans and wooden spoons. Hey if this works, to kill the Iron beast, they might herald me as 'the Iron Maiden', as long as I don't end up looking more like Eddy).
Basic plan would be to sit on the mud bank close to the waterline, playing a rhythm to summon the beast. Hopefully the sound ripples across the surface and underneath and provokes interest by the beast to come over.
I am trying for this effect. In the circumstances, it seems most appropriate.

The very worst will be using my spiked spear as a matchstick beam to keep the crocodile's jaws open rather than biting down on me.
If drums are available or I need to make my own percussion, I will spend the evening working on fine tuning any of those items so they make a solid pitch in their bass sounds.
If needed.
