Hello Kitty World

Hello Kitty World is a reskinned port of the Game Boy game Balloon Kid (which would itself be released much later as Balloon Fight GB via Nintendo Power kiosks in Japan), itself a sequel to the Famicom's Balloon Fight.

Notably, the game does not have the Balloon Trip mode featured in its predecessors, nor does it credit Nintendo (though the "Mario Co,Ltd" listed on the title screen is probably an indirect nod).

Unused Music#

Perhaps not surprisingly, a few of these are Balloon Kid tracks reworked for the Famicom.

• The factory/Stage 8 music, with a short recurring song element from Balloon Kid at the beginning which was not present in the original. Hello Kitty World instead uses the more cheerful Stage 1 music for Stage 8.

• The intro sequence from the beginning of Balloon Kid for when Jim is floating away.

• The Balloon Trip end jingle.

• The Balloon Trip Giant Bubble jingle for stopping the time.

Sound Test#

After completing the game, you will be greeted with a "the end" screen. If you press A + B + Start + Select fast enough and correctly, you will unlock a hidden non-visual sound test. Press Up and Down to select the track (including unused ones), and A to play the selected track.

Oddities#

The music played in bonus rooms resembles one of the tracks from Nintendo World Championships 1990, except the intro is different. The intro in Nintendo World Championships 1990 features a brief rendition of the Super Mario Bros. overworld theme, which might be why it was changed. It also resembles the track used in the PlayChoice-10 Virus prototype of Dr. Mario.
