I get the fact that you have to pull in the opposite direction and all and constantly pull it back and forth, but what is the best way of going about it? In most cases i have a hard time catching the painting ghost super fast, and yes i'm in the hidden mansion.

You want to hold the opposite direction of the ghost for 10 frames (hp drains 1 per frame for 10 frames, then 1 per 10 frames after that), then put the stick back to neutral quickly (optimally 1 frame), then hold it away for another 10 frames

Thank you skozzy!!

No problem
