Hmmmmm
I'm not too good at the LC, and I know Grundo seens a little obvious.... but I'd go with the number 22. Neocola is bought in a
shop and the Grundo bought it, so it would have been purchased in the Grundo shop (as a guess...) and if you go to the Grundo shop, the number 22 appears in the web address? And the number 22 s in the grid?
I know it's a long shot, but there's just as much evidence that it's a grundo as the rest of the neopets. And they could put odd numbers in there to throw you off. Theres just as much significance in 127 being in the list as there is in all the numbers that are excluded. I'm gonig for the Grundo, as it's the only neopet I can think of that has a direct link with the Space Station, and a number on the list. I'm only down 400NP if i get it wrong
