Alina makes custom phone cases for a tech store. Each case has a design and a keychain.

The phone cases can be made from silicone, leather, or plastic. Alina has keychains: bear, dinosaur, raccoon, and fairy - and she can draw the moon, sun, and clouds on the case.

Alina is happy only when three cases are displayed in a row from left to right according to the following rules:

- There must be a silicone case with a bear keychain;
- To the left of the case with the bear keychain, there must be a leather case, and to the right, a plastic case;
- The three cases in the row must have different materials, keychains, and designs.

How many ways can Alina be made happy?
