an angelgotchi a a type of tamagotchi that was made in 1997. THis was made because parents didnt like the idea that tamagotchis "died" and little kids killed them. So, bandai made a solution to the prob. Angelgotchis were realesed.
If your interested in buying one ( i also am ), check on ebay. THe price range is about 30.00 to 35.00$ THere are japanese and american ones. American ones will cost more.
These tamas are considered rare. So, if you get a good offer, take it, because you dont want to miss the chance.
