No problem, I’ll put it in a summary:
How to catch the Egg Clowns
You first need to unlock the Lamppost building from the upgrades tree. Then, while you’re in a level with an Egg Clown, mouse around the darkness until you hear a loud, rasping laugh (or look for a clown glimmer with a blue party hat).
You then need to place a Lamppost close to that spot, which will reveal the Egg Clown in dim light and cause it to fight you instead of run away.
