The modern bed set with Sonic Tails Knuckles & Shadow running in CG on the front of it is 2 sided, even though most product photos don't show it. Here, you can see what the other side looks like.

The comforter / blanket has rings & chaos emeralds all over in a scatter pattern. The top sheet has CG rings in a row & Sonic graphics. The fitted sheet (middle) has characters scattered on a light blue background. You had to buy this in 2 parts. The big blanket is always separate. The sheets, pillow case & fitted-sheet are always packaged together. This is shown on a twin bunk bed.
