This is a thread for players to try things and figure out how to get stamps! You can find yours in User profile > Stamp collection (or use this direct link)

This post will be updated with methods to find stamps if it's not described in the stamp collection page. This will be spoilers so don't read any further if you want to try things on your own!

If you're looking for a specific stamp and the description on the stamp collection says (???) that's a hidden stamp! Post here so we can figure it out together!

If you know the method to unlock a stamp, post on the thread and tag me! I'll update the first post and credit it to you.

Thanks wit!

Thanks thy!

Hidden stamp: alleyoops
Encounter the Mysterious Alleyway during April Fools

From the stamp collection description

It's called scienceishappening; the obtainment method is (spoilers, obviously lol) to mutate a pet. This uses either the suspicious concoction (obtained mostly through the voice in the fog) or the devious brew (obtained with pumpkins in the Halloween event)

Thank you

Hey everyone! I'm reusing this thread and opening to everyone that wants to try new things and figure out how to get the stamps (new and old)

I'll mark it as a spoiler thread in the title

there's a stamp between heartcloud/curious and numbergroup/papertree/voiceinthefog, can anyone confirm if it's 'devious' for getting one of the halloween void forms?

I used the two devious brews I had and didn't get a void form, so this is open for anyone else who still has one to try

@Eternitydeath i can confirm it's not devious — that stamp is under the 'pets' section, not 'other'. maybe the stamp info page might help clarify things? ¯\_(ツ)_/¯

@wit oh! yeah, it would've taken months for me to randomly stumble on that on my own, thank you :)

@Eternitydeath you're v welcome!! i'm the type of person where i immediately went to look at the info pages when we got them, and was pleasantly surprised to be rewarded for it
