First of all, keep this 1000-piece 19”x27” GREMLINS puzzle out of the sunlight. It'll fade.
Second, don't give it any water, not even to drink. Puzzles don’t drink, and besides, that’d damage Matt Ryan Tobin’s magnificent Mogwai artwork from his 2016 Mondo poster.
But the most important rule, the rule you can never forget: no matter how much it cries, no matter how much it begs – never work on it after midnight. (Your preferred timezone is up to you.)
