Does the penguin fly? Mass/per/volume is a thing...

Mass per volume is density, and I suspect the Trex and kangaroo are similar (~1000 kg/m^3) so yes they'd both bounce in that case. I think what you're looking for is surface area to volume, which decreases rapidly as an object gets larger while maintaining geometry.
