STUCK ON KINGS QUEST 1

[R4L]

What do I do after I get the chest from the giant in the Land of The Clouds? I currently have in my inventory:
Leather pouch full of diamonds
5 rocks
A bucket full of water
A golden egg
A carrot
A golden walnut
A dagger
A golden key
A four leaf clover
A bowl
And a ring that turns Sir Graham transparent
Please help!
