ハローキティのポンポンパック2

I do not have reliable historical information about Kokoro Company, Ltd.'s "ハローキティのポンポンパック2" beyond the brief description provided. I can confirm that it is described as a bagged popcorn vending machine featuring Hello Kitty voice, song, and dance behaviors during heating, but I cannot verify its introduction or discontinuation year from my current knowledge.

Because I cannot confidently identify primary-source details for this specific model, I am leaving the timeline empty rather than guess. If you have a brochure, press release, or product listing with a date, I can help turn that into a proper history.
