I think that you should do igloo items so if someone got there first membership they could have a brand new igloo item.
Maybe like a goose or duck decoys with a grass flooring, or one of those benches that swings. Or a big roll of duct tape sitting on a table.
(Also, what do you do with the speedboat? Is it a clothing item? Or is it one of those things that you wear so you san use it in a game, sort of like the surf board?)
