Rediscovered obscure Godzilla game!

Today, I was just searching through the Japanese internet, and I stumbled upon a strange Godzilla game I'd never heard of before. The game, called Gojira: Doki Doki Kaijuu-to!!, which loosely translates to Godzilla: Heart-Pounding Monster Island!!, was released for the Sega Pico in Japan in 1995. The Sega Pico is a somewhat obscure game system released by Sega in the mid 1990's targeted for children in the 2-8 age range that featured mostly educational games.

Gojira: Doki Doki Kaijuu-to!! features a surprisingly large roster of monsters, all of which are done in a chibi-style. The game consists of a few "hub" levels, each of which feature some mini games centered around the game's various kaiju, all of which are very easy and simple, as is to be expected for a game aimed at young children. The most interesting thing about the game is simply its monster roster, which includes Godzilla, Little Godzilla, Mothra, Sanda, Gaira, Gorosaurus, Biollante, Kumonga, Kamacuras, Dogora, Baragon, Manda, Ebirah, Giant Octopus, Battra, King Ghidorah, Gigan, Megalon, SpaceGodzilla, Mechagodzilla, Rodan, Anguirus, Varan, King Caesar, Hedorah, M.O.G.U.E.R.A., and a new monster called Yoganzee.

Here's an image of the game's title screen:
