Neddie, the tinychao Chao by @chrigavl (Christine Gavlas)
Having bought myself Sonic Advance for my birthday, (well, I got it yesterday, and I'm 20 today) I hastened to examine the Chao aspect of the game, and named the wide-eyed jellybean I found in the garden "Neddie", in honour of the sad extinction of the Goon race with the recent death of Spike Milligan. sigh
whatever it is, it's ADORABLE! ^_^ hehe
