Name of Famicom Game

I was just thinking about this game that I saw in a Japanese videogame TV show. I remember it particularly because it had the mascot for some type of chocolate candy that I saw at my local Japanese restaurant. It was some type of weird looking bird. I seem to remember that it was rather rare, but I could be wrong about that. Does anybody know the game I'm talking about?

 

Specifically Kyoro-chan Land, just a Japanification of the Western game Castelian.

 

Yes, that is indeed the game I am looking for. Thank you.
