Hi D.C.,
I might be able to find you a copy... I have to go shopping for manga for some customers so I could add tekonkinkurito to my list!!
As a previous poster said, don't despair if some manga seems difficult... I would recommend that you try easier manga, or manga based on animation films such as those by Miyazaki, which you may have seen.
A lot of manga use furigana to help their readers deal with the kanji readings - even elementary kanji in many cases.
Anyway, good luck with your Japanese studies!
