I've been looking through all the forum posts asking for help with various items, but I haven't come across anyone asking where to find this item, which sort of makes me feel dumb, but here goes:

Danger 3-1-2 (with all available DLC)
Slingshot appoximately 19cm

Can anyone give me a clue as to which level(s) this item can be found in and an approximate location?

EDIT: Thanks for the suggestion, Vix. I started going through the different Candy Shop levels and found the item at the corner of the large stand in the middle of the toy stand in Delightful Dirigible.

100% Collection attained!

i would guess off the top of my head and say any of the levels that have you starting in the candy store, like sunrise.

do you have the dlc? perhaps there's one in fancy's.

if i get the xbox hooked up to look for the other users item, i'll take a gander for yours too. :)

edit: sorry i didn't get to check in time, at least you found it via my guesses. :)
