Adobe Illustrator used to have an Effect → Warp tool called Crystallize, that was good for creating starburst shapes & effects, like this:

It seems to have disappeared in the last few years (actually, sometime between 2015 & 2018). There's a totally different tool by the same name (Effect → Pixelate → Crystallize). There's also a similar, but slightly different tool with a different name (Effect → Distort & Transform → Zig Zag). There's also the Star shape tool. But none of them are quite the same.
What happened to it? Has the name changed?
Has it been removed? If so, how best might I emulate it?
