Use Newton to give it a more realistic look of interacting with a floor/ground
Take footage of a real gazelle jumping, track using using Mocha and the apply track on letters
Use Duik tools or AE's new animator features to create puppets from your letters and link them as a skeleton - then animate the whole thing and have the move affect all letters as a whole...
That's what comes to mind for now.
Hi. You might look at Bezier Warp effect. Go to the stop point and keyframe everything, then move back a few frames and make the arc you want it to travel, then keyframe the text position off to on. It will curve along the arc then flatten out. (That is presuming you don't want to simply have the text follow a path.)
