Hey @Stephen427! @WesleyT245 is right, if the frogs hit the pole and the pages didn't fall down, that's definitely a bug. If you don't mind, reply with your device model and operating system version and we'll look into it. Also, make sure your version of Epic 2 is up to date!
I've had one other person report a similar bug and we found that if you beat the frogs in a different order, they'll make the pages drop. Try completely resetting your device, then starting the level over and beat them in a different order to see if that helps.
Thanks and sorry for the inconvenience!
