If the next level in Save Misty, Odus Birthday Bash or Bananadrama doesn't open even though you have all required Pufflers, Jelly or Monklings then something sticky is going on.
First make sure you have the latest update installed from App Store, Google Play Store, Amazon Appstore or Microsoft Store.
If you already have the latest update, then try with reinstalling the game.
First make sure the game is connected to your Facebook or a King account so your progress is saved
Then delete the app
Restart your device and download the game again
Finally open the game and reconnect it to Facebook or to your King account to get back your played levels and gold bars (boosters and lives will be lost when you delete the game)

I tried updating the app and it didn't work. I reinstalled the app, and it put me back to 0 completes for the achievement, even though I had completed two monkling levels. Ugh.
@shauntellp if you see a paintbrush on map, it means you have completed the game until this momment. Wait until Wednesday and continue your adventures.
