Kero Kero Keroppi no Daibouken, or Kero Kero Keroppi's Big Adventure, is a Japanese-exclusive Nintendo Entertainment System game featuring the popular Sanrio character, Keroppi. The game's gameplay is a side-scrolling platformer where players guide Keroppi through various levels, collecting items and avoiding enemies. While details about the original development team are scarce, it's a product of the era when Sanrio actively licensed its characters for video games. The game's charm comes from its bright, colorful visuals that are typical of the NES era and its connection to the beloved Keroppi franchise.  Its English translation patch adds accessibility for international fans who appreciate both retro gaming and the Sanrio universe.
