Second Land of the Lost movie?

I saw the start of a movie or something on the tv in the break room at work, yes, be jealous and it looked like Land of the Lost, had an intro sort of cut out paper styled (don’t know how to say it) with things like the sleestak and t-rex from land of the lost, went into a classroom after a presentation, and someone left an egg on the desk, they put it on a cup of coffe and left, and then a mini sleestak started hatching. What movie is this?
