First and foremost, thanks for creating the Icerink archive. Without it, many files could have been lost forever.
Second, do you plan to always keep this archive up?
Third, there are some mobile files that are missing. I see you have the "paper/image" directory here, but you're missing the following directories:
paper/icon
puffles/paper
puffles/hats/player_card
furniture/icon
igloos/buildings/icon
igloos/flooring/icon
igloos/locations/icon
Fortunately, the Internet Archive has them: http://web.archive.org/cdx/search/cdx?url=http://media8.clubpenguin.com/game/items/images/*&fl=timestamp,original&collapse=urlkey
Also, although not even near complete, other mobile files can be found here if you're interested: http://web.archive.org/cdx/search/cdx?url=http://media8.clubpenguin.com/mobile/*&fl=timestamp,original&collapse=urlkey&filter=~!field:config/catalog&filter=~!field:assets/catalog
(Note: I filtered out "config/catalog" and "assets/catalog" directories from results since I see you already have them here.)
Specifically, "payloads/minigames" would be nice to add to the archive.
By the way, no need to add me to contributors.
