Dung beetles roll balls the size of a truck.
Fleas jump half a meter (for us a kilometer). An elephant can't
jump. An ant survives microwaving and a mouse falls unharmed
from a plane.
The riddles are questions of scale.
The mass of an object is proportional to L3
The strength of muscles is proportional to L2
The height of a jump is proportional to L3/(L2 x L)
