See the model
A brown treasure chest with a gold band, a hidden treasure and a lift-off curved lid. Open it, hide a clue and send someone on a treasure hunt.

Match the shape, size and colour to the parts pictures. A stud is a round bump on top. Count rows and columns from one edge.
New pieces keep their full colour. Earlier pieces are lighter. Keep the front of the model facing you unless a step says to turn it.
Gather all the pieces first, then take each step at your own pace. Help your child press pieces together and lift removable parts gently.
The lid lifts off; it does not hinge. Ease the plate off the rim with an adult.
The eight narrow wall bricks are 1 × 2 double-height bricks.
Gather pieces
Colours show the pictured version. Cream represents Tan and brown represents Reddish Brown. Match shapes and quantities first; other colour choices have not been checked for this edition.
