The game begins like any other normal day for the family members - father Taneo, mother Etsuko, daughter Ririka, and son Tsuyoshi - until strings of events stand as obstacles in their way of returning to Hatsu's with the presents.

The boulder emerges again through the building's main entrance, but he easily evades it - not long after though, a piece of the statue which was holding the flagpole lands on his head, knocking him unconscious.

After answering the questions correctly, they accidentally send Taneo - still strapped to the stretcher - out of the ambulance and into the traffic, due to their over-excitement.

Etsuko manages to remove its head using her groceries, causing it to explode and launch her and the robbers through the back wall of the bank and out into the snow.

He must then run away from a ravenous antlion while avoiding mudslides, then escape a spider's web, and following an encounter with the unfortunate boat owner who helped Taneo earlier - in which Tsuyoshi, too, unplugs the block and nearly causes the boat to sink - he has to escape pursuit from a praying mantis, after which a friendly ant leads him through a series of underground tunnels straight to Hatsu's backyard.

Wanting to go there, Ririka makes her classmates switch seats (causing many of them to be knocked out by chalk thrown by the teacher) so she can get to the exit.

While she's getting ready to have hers taken, a tiny UFO appears in front of her, upsetting her and causing her picture to be printed on the teddy bear with an angry frown.

Ririka yells at the UFO and tries to capture it, but it shoots beams that cause different things to shrink or grow at random, one hitting the teddy bear dispensed out of the machine.

After Taneo agrees, Ririka goes to the screen and plays a game of Simon Says by pressing the colors on the small UFO matching the flashing colors of the mothership, interrupted by a "Please Wait" sign and a news story of the giant teddy bear attacking Tokyo, the bank robbery Etsuko witnessed, and the big boulder, with Ririka's teacher throwing chalk at it.

After Ririka gets to her destination (and the UFO shrinks the boat, leading to its owner's encounter with Tsuyoshi), she takes a delivery bike leaning against a wall and rides away from a crane/bulldozer manned by the bank robbers and their leader.

Managing to outrun the criminals, who meet their fate as the crane runs off the road into the water, Ririka and her bike are lifted into the sky into the mothership (silhouetted briefly against the moon in homage to E.T.

The design and script was done by Kenichi Nishi, a director at Love-de-Lic and future co-founder of Skip Ltd. known for his unconventional approach to game production.

[4][5] The game's art director was Naozumi Yamaguchi, a former Human Entertainment employee who would later go on to work with Sega on projects such as Phantasy Star Universe.

[6] Titus Interactive acquired the rights to publish the game abroad, and introduced it as their only PlayStation title at the Electronic Entertainment Expo in 2000.

[citation needed] Two minigames, which involve bomb disarming and karaoke respectively, were removed from the localized release of the game, reportedly because they relied too much on kanji and Japanese language, making them difficult to translate.

[9] According to Media Create sales records, the PlayStation version sold 70,760 units by the end of 1999, making it the 184th best-selling video game in Japan for that year.

[29] Jess Ragan of 1Up.com, in his retroactive review, felt that the game, for its time, was an innovative introduction to mini-game compilation titles.
