Girl, i am sorry, i looked everywhere in the world for some ideas on how to do this and you had to buy all of them…man oh man, these projects just get harder and harder the older they get, i feel for you, all i can think of is draw the background you want on the poster, then on seperate paper draw the saber toothed cat and color it or whatever, cut it out, then clue some card board or something that can make it stick out from the poster. onto the back of the cat drawing then clue the cardboard sticking out from the back of the picture of the cat to the scene you drew……man, good luck with this, hope you find some ideas

Best I can think of is to try playdoh. You could draw all the background and draw the saber-toothed tiger’s hind legs outstretched, then on a separate sheet of paper draw all the rest of it in a pouncing position. Then just cut out the torso part and work it like one of those pop out cards. It will look kind of like it is jumping out of the poster. Good luck with that project!

If it is available where you are, try to get some Crayola Model Magic. It is easily moldable, light, air-drying, comes in several colors, and can be painted once dry. (And it can be glued to posterboard or heavy cardboard–it’ll stick, at least for a while.) I’ve used it for this type of project myself.
