gifting has the extra motivation of getting to 888 gifts to get a special base, as a result we can see a lot more gifts are being given out then people are giving out poops, but the same amount of poops are needed to unlock the tiers of the shop.
so my suggestion would be that pooping in 888 dens should get it's own reward, (like a mud based base or something?)
I think this would make the poop-to-gift ratio a lot more balanced when unlocking stuff.

Obviously it'll all be unlocked eventually, just figured it would make sense to have that bonus poop reward.
