Tumblepop[a] is a 1991 platform arcade video game developed by Data East first published in Japan by Namco, then in North America by Leprechaun Inc. and later in Europe by Mitchell Corporation.

Starring two ghosthunters, players are tasked with travelling across different countries, capturing enemies and throwing them as bouncing ball, jumping on and off platforms to navigate level obstacles while dodging and defeating monsters in order to save the world.

Tumblepop is a platform game reminiscent of Bubble Bobble, Pang and Snow Bros., where players assume the role of ghosthunters through ten levels consisting of ten stages set in different parts of the world (Moscow, Egypt, Paris, New York City, Rio de Janeiro, Antarctica, Australia, Japan, Space and Moon), each with a boss at the every tenth stage that must be fought before progressing any further, in an effort to defeat monsters, ghosts, aliens and other oddball characters as the main objective.

[2][3][4][5] Any enemies the tumbling ball rolls into are eliminated and reveal hidden bonus items that are crucial for reaching high-scores such as collectable letters of the alphabet found in randomly appearing bubbles to gradually spell the word "TUMBLEPOP", the progress of which is permanently displayed at the bottom of the screen.

Getting hit by enemy fire will result in losing a life, as well as a penalty of decreasing the characters' firepower and speed to his original state and once all lives are lost, the game is over unless the players insert more credits into the arcade machine to continue playing.

[6] Hidemi Hamada, Kei Ichikawa and Minoru Sano acted as programmers, while several artists like Atsushi Takahashi, Chie Kitahara, Hiroshi Tada and others were responsible for the pixel art.

[11][13] In Japan, Game Machine listed Tumblepop on their 1 December 1991 issue as being the eighth most-successful table arcade unit of the month.
