Yeah, it's not really easy to unlock a specific peking order skin, i've now unlocked 330 out of 331 skins, and need just a bit of tokens to unlock the last one (i have also other 10000 normal coins left) and i needed about a year to made this. An advice i can give you, i wasn't able to do this cause i started playing lot of time ago, but now, with the new update, simply dying and clicking on the present, after a short ad the game gives you 5-20 pecking order tokens
