I have had a really hard time finding a good guide to Wendell's goods that is complete and includes all the pertinent information regarding what is available and what you need to feed the insatiable walrus to get him to give up said goods.
So I went on a little time traveling foray and would like to offer up my findings to the fine folk on this board.
Please refer to the links to see images of each pattern. The letters and numbers on the patterns are simply for reference and do not appear on the actual pattern.

To get a pattern, you need to feed him
one of the items listed for that pattern.
