Before parents started giving smartphones to all their newborn children, LCD handhelds with monochromatic screens were the next best thing if you wanted to play a Crash Bandicoot mini-game on the go.
McDonald's Pretty Handhelds

McDonald's Ugly Handhelds(contributed by CB911 and Tikous)
5 Happy Meal handhelds with an overall sloppy external appearance.
Quest Classic Arcades(contributed by Crashnconker, Nega, and CrashRatchetFan)
These small arcade machines play like the classic Frogger game. Just guide Crash through a series of moving obstacles from the bottom of the screen to the top.
Quest Ruler Handheld(contributed by Crashnconker and Nega)
Another Frogger-type game by Quest (because we all know there weren't enough of those), this time presented on a flat handheld that also served as a ruler. The punches on the left allowed you to keep it in a file folder and play it during class. Who needs math anyway?

Tiger Handhelds(contributed by Crate Balls of Fire and Ruination)
These handhelds were produced in 1998, possibly before Crash 3 came out (they did use Crash 2 art). The second one has Crash running down an endless path. You can make him go left, right, jump, and spin. This particular handheld has a graveyard setting. Obstacles you'll encounter include snapper plants, ghosts, rats, and coffins you have to jump over. There is a total of 3 stages. At the end of stage 3, you get a key and the face of a mysterious scarecrow appears.
Arm Handheld(contributed by Crashthebandicoot and Orange Baron)
A handeld with a strap that you can place around your arm. One variant has Crash avoiding boulders and crossing a river by jumping on different rafts. There are 3 stages with increasing difficulty.
