I seem to recall reading that Mareep was named for a popular Japanese song about a 'merry sheep'...

Wheres the art
Where did we get the HGSS artwork from? In fact, where does any of this artwork come from?- unsigned comment from Max King (talk • contribs)
- It fell off the back of a truck. If you'd checked, Maxie, you'd see that most of them came from the Pokedex.co.jp site; I think the HGSS are from the official site. —darklordtrom 23:01, 30 June 2009 (UTC)
Platinum sprite is incorrect
I know I've already mentioned this on the Natu discussion page, Mareep's color palette in Platinum is different than D/P. Therefore, the Platinum sprite displayed on the page should be considered false information. Chaos Rush
These are the differences:
Diamond/Pearl: 
Platinum:

EDIT: I uploaded the new 179.png, but I don't know how to change the file displayed under "Platinum"...- unsigned comment from Chaos Rush (talk • contribs)
