Hey, all I remember about this (because I was about 4 years old when I used to watch it) was that it was a cartoon, very roundy and cute style drawings, it had these 2 kids, brother and sister I think, who lived at home, and they would eat 'magic' cookies and go into their fridge and end up somewhere with these cute dinosours? I think! Something along those lines anyway...
Anyway it'd be so great if anyone could let me know, thanks!. I can also remember something about bright white trainers (sneakers) thanks for any replies :D

I don't know if this is it, but it sounds kind of close.
Click Dragon Tales (http://pbskids.org/dragontales/index_sw.html) to find out for sure.

Thanks anyway but its not that, I was a little older when dragon tales was on.. I'm 20 now. :)
