Umm... this game has too many premium things. If someone buys something, they can still be robbed, so In my opinion, there should be a way to get coins for free. 7-day-streak daily bonus, maybe?
I think Kongpanions could be buyable because:
1. Newer players (say, 1 week from now) will never get the patty (nor shiny)
2. There will come show-offs ("Old" player: I have X Kongpanions and you don't! You suck!)
3. The completionists would be glad. I missed god-knows-how-many kongpanions, and it's driving me nuts!
If you agree give it a "+"
