I'm not quite sure what this is, but it should be easy with my awesome instructions.
Step 1: Step 1
Start with your basic lego base.
Step 2: Step 2
Add 2, 2x6 blocks laying them with the short ends touching. Repeat this step parallel to the first blocks, leaving 4 spaces in between sets.
Step 3: Step 3
Add 2, 4x2 blocks to create a rectangle.
Step 4: Step 4
Complete steps 2&3, 3 more times until wall is 4 blocks high. You may use other sizes of Legos to add up to the right size if you cannot find the correct size of Legos.
Step 5: Step 5
Using 4x2 flat pieces, cover the open center of your structure.
Step 6: Step 6
Add a door to the very center of your structure.
Step 7: Step 7
Add 2 eyes to the front center of your door. And you're done!
