Kids o' Boredom 4

This movie occurs chronologically after Kids o’ Boredom 3 ½, which came out after this. Ethan hurt his arm so he’s in a cast, and the kids go back in time to prevent this. Despite this, the Hunters alter time and make it so the past three adventures never happened. The kids, alongside Mr. Trenterasaurous, who is now nice to the kids and even helps them change time back to normal, have to fix the timeline and save the history of boredom! Can they change Kids o’ Boredom 1, 2, and 3 back to the way they were meant to be and defeat the hunters?
