I thought it was the prize for Level 9 of Leviathan Harpooning. I finally beat level 9, no prize. I check the achievements page and no prize is listed for any tiers of the game but then I check SubetaLodge and it has items listed as prizes for beating levels 3, 6, and 9 (Bitter Harpoon Cannon for 9).

I guess the prizes were removed at some point? Is there any other way to get it?

I'm not sure, but it may be worth mentioning on the "Items to put back in circulation" thread to ask if it was removed from the game or if it goes out in some other way. This is probably something that could look into and maybe figure out what to do with it if it's true that none are going out anymore for some reason.

Thanks!

When/if you find out, could you please let us know if we need to update the entry at SubetaLodge. Thanks!

Sure thing 😄
