# Equation of a 3D egg [duplicate]

Does anyone know the equation of a 3-Dimensional egg. Like a real egg( the uneven type where it is more wide on one side), not an ellipsoid in 3D cartesian form.I can't seem to find it anywhere, I mean there is one even for the heart in 3D, so there should be one for an egg right?

$$\begin{cases} x(u,v) = (1 + 0.2 v) \cos u \sin v \\ y(u,v) = (1+0.2v) \sin u \sin v \\ z(u,v) = 1.65 \cos v \end{cases}$$
