The last level and the waterskin

[Johnny]

I reached the final level by the cheat code and I've printed the walkthrough but couldn't find out where can I get the small waterskin from
Please help me NOT releasing that ugly creature

Moral of the story? Don't skip levels...

The item you need can be found 4 or 5 levels previous to the one you're on, 'The Mastabas'.
