Game Boy · 1994
About this game
It's REX To The Rescue! You were once just a typical Tyrannosaurus-10 tons of terror with lots of teeth and really bad breath.
Now, thanks to Captain NewEye' Brain Grain formula, you're the intelligent giant reptile called Rex - and you're hopping mad! Evil Professor ScrewEyes has "dino-napped" your prehistoric pals, Woog, Dweeb and Elsa, and is holding them prisoner in his castle.

Only you have the brains and brawn to set them free!
Follow a mystical map that will take you from the outskirts of the Jurassic Jungle through the Cretaceous Caves to well within the castle walls.
Then it's on to the Dungeon and, if you avoid extinction, up into the Tower. 16 levels of "brain-draining" obstacles, traps and other dangers await you-not to mention power-boosting inventions, carefully hidden bonuses and secret worlds of adventure.
So step on it big guy-or your friends could end up as colossal fossils!
About Game Boy
The original Game Boy (1989) proved that handheld gaming didn't need cutting-edge graphics to succeed — its monochrome screen and legendary battery life, combined with Tetris as a pack-in, made it a cultural phenomenon. Game Boy cartridges are famously durable, so this remains one of the more accessible retro platforms to collect, though translucent color variants and complete-in-box copies with the original brick-sized manual add real value for condition-focused collectors.
Gamevaro tracks Baby T-Rex for Game Boy with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Baby T-Rex to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This GB release dates back to 1994.
