I think it would be kind of cool to be able to hide little gift-y type items underneath dirt piles or bogs or behind rocks, so that when you are digging or mining, you might find a little surprise left by someone else. I know that the game already gives some surprises when you are doing those things--I just really like the way that players can hide gifts and I thought this might be an additional layer for that. (And thank you to whoever left the frog cubimal behind a tree in Tamil. He's my first cubimal and I'm taking very good care of him!) I love that this game has so much "nice"-ness in it!
