OK so it wasn't multi-format. I don't know why that description is there. It is a straight blu ray package with 4 episodes per disk, all 5 seasons.

Also contains a special feature for each episode and then each season has extra features as well. The covers are different than the pictures too. For example, season 1 is a picture of the sea horse, leaf, and frog as a 3-d hologram. Definitely different than you, OP. I wonder if we have different special features.
Nonetheless, it's the complete blu ray package for $50.

So you don’t have to go through Facebook
I would say if you are a fan it is well worth it to get the box set. It is not very expensive and honestly the show looks great on Blu-Ray.
