I recently purchased the game Tonky as part of a lot deal of X1 D games (about half were 3" floppy disks and the other half tapes). This is the most intriguing game to me, and it doesn't disappoint. This article is more about the physical aspect of the game. I have more detailed information about gameplay in the Tonky game introduction page.

The packaging is unique. The outer box has a window on the pig's rump that shows the inside of the package, which includes a tray with the game disk and a stack of sheets of paper. The top page displays the system info and price, which is what you see in the window. Underneath that is a loose-paged picture book. I like the packaging, but you do have to be careful with it so you don't snag any corners of the illustrations. The floppy itself is reflective silver with blue letters, unique for this system where most games are pink and white because they mostly come from Hudson Soft.

The picture book outlines the story of the game and the stages as you progress through them. The artwork looks something like sribbling at first glance, but the elements are still clearly defined and fairly cute-looking, though I am slightly biased as I like pigs.

Here are some in-game screenshots but there is more detail on the aforementioned Tonky game introduction page.
