# In sp² hybrid orbital, why does the p orbitals only have 3 sides instead of 4?

Usually two separate p orbitals would have '4 lobes' while in a $\ce{sp^2}$ hybrid those 2 p orbitals would only have '3 lobes'. why?

I'm referring to diagrams such as the one shown below:

First, an $sp^2$ orbital does have two lobes. One is large, and one is tiny. Secondly, $sp^2$ means "a 'mixture' of one $s$ and two $p$ orbitals". Like the following:
There are a total of six lobes here, but they are distributed amongst three $sp^2$ orbitals.
