Jakub is using a lot of nested repeat blocks in his code.
The tunnel through the tree must be 2 blocks wide, 3 blocks tall, and 4 blocks deep.
Jakub has already figured out the code to the right.
When he runs this code, the tunnel is too narrow for his horse.
Can you spot what he's doing wrong and fix it in your code?
Is it possible he forgot a nested block?
You can right click on a nested block and click "duplicate" to duplicate that block and anything inside of it.
All the blocks you need are already in the Intern's code.
