Jack in The Box is a Fast Food chain in the USA, although it is not everywhere in the US. It tends to be toward the western side. They had a "Jacks Kids Meal" promotion with Sega PC, and included some general famous Sega toys. So BUG! got in, along with Ecco the Dolphin. Sonic is a "Rolling Racer" and Knuckles is a mysterious "action figure" but what does he do? Answer: Nothing! It is basically just a statue. Thanks to Cornboy for the detail info on this item.

Also released were actual games you could buy for the PC through the promotion. (game disks are uncommon)

In the gallary is a close-up of the rolling racer. It is a "pullback n' go" format toy. The graphic is one of those stickers that is unfortunatly easy to peel off. (so be sure to check before you buy one) The sticker may look lenticular, but it is not. Thanks to Cornboy for the detail info on this item.
As you can see, the knuckles does not appear jointed at all, and who painted the eyes? He looks like a zombie...

Here's the actual game you got, if you bought their promotional item. "The games sold for $1.99 if you bought a kids meal and I *think* $5.99 if you bought them individually" They came in a paperboard sleeve, and were released around 1999/2000. (Which explains 3D blast, by this point, Sega didn't mind 'giving it away' as SA1 was set to blow it away. Game info and photos provided by Darxide.
The game looks like an exact copy of the original, except with the JIB logo.

Remember the Jack in the Box Sega promotion from the top of this page? Well here's a photo of the meal bag that went with the promo. Since it's just a paper sack that had fast food in it, almost no one ever kept them, so this is interesting to see. The bag has a "Sonic bustin' thru" effect with rings going all over. But look at that super strange looking Knuckles! Ecco the Dolphin & BUG! are also peeking around in the background. Inside, you'd find that little card (not a pamphlet) that explained the other toys.

The bag is all checkered at the bottom (seen on sides) The 2 toys are profiled elsewhere on Sonic Fast Food. The sides of the bag had "kiddie games" activities to do. Sonic looks at a pile of rings (how many?) & if you connect the dots you obviously get BUG!. The other side has more super odd looking Knuckles (That art is rather mutant) , with Sonic in a maze race to a ring in the center. It's very interesting to see everything that went with this fast food promo.
