Trunski is a Game Gear game developed by Core Design. Not much info exists on the game online, but it was featured on the Consoles+ magazine. The game was ultimately shelved.
The text translates to: Trunski is an elephant. After a little tour away from his native jungle, he returns to realize that it is now populated by infamous rhinoceros. Under the leadership of Rhinus P.ltus, they plan to set up a mining installation in the middle of Trunski's territory. In summary, this platform game is non-violent, humorous, & politically correct.
