Grub help please

[Sheepo]

Seeing as I just became able to play ep. 2 can anyone hook me up with a decent guide for the grub achievement? Can you unlock it with commentary on? Because I could've sworn I saw a youtube video where a node said, "BTW, you should (#) many grubs killed right now".

Any help would be great

This one's good and easy to follow. Only text, but it worked for me.
