1. First, start splicing from the feet. Overlap a 2-by-3 brown building block with three 2-by-2 blue building blocks as Mario's foot, then make the other foot, connect the two feet with a 2-by-4 blue building block, and then overlap a 4-by-4 building block to fix the two feet.

2. Secondly, a 2× 4 blue building block is superimposed on the top building block, next to which are two yellow building blocks of 1× 4, and a white building block of 1× 2 is superimposed under a 4× 4 white building block as Mario's hand. After repeating the above steps, splice next to the yellow building blocks, and finally superimpose a 2× 8 red building block.

3. Then, according to the red building blocks in the previous step, add two blue building blocks of 1 times 4 on the sides, take out a red building block of 2 times 4, stack two blue building blocks of 1 times 4 in the middle of the top, and finally stack two red building blocks of 2 times 2 on both sides. Take out two red 2× 4 building blocks and put them in the middle of the top of the building blocks. Put a blue 1× 4 building block on both sides, and then put a red 1× 2 building block next to it, so that the lower body is completed.

4. Then, start splicing the head, starting from the bottom of the head, splicing a layer of yellow-brown building blocks and overlapping a layer of yellow-black building blocks. On the next floor, white blocks were added to make Mario's eyes, and brown blocks were used to make Mario's hair. Then three layers of yellow and brown building blocks are needed to splice the head.

5. Finally, at the beginning of the hat splicing, the five-layer hat is spliced with red building blocks as shown.
