Thesingingsparrow uses the Item Worth Scam. They host a giveaway, saying they're quitting and offering their list for specific items that their sister wants. Their helper, tj06670, has an item (for example, a pink Violin), and says so right away.
However, they won't take the spikes that Sparrow is offering, saying they don't like the colors. They want a Pink or Yellow Long. If a user offers them any of these, they'll accept. The user will expect Sparrow to trade them the Purple and Green Long for their violin, but the den is locked instead.
