Stone Monkey - how Tf do I kill this

Hi all,

Having a really hard time getting past stone money. The first version, I can smash him - but the 2 versions I just can’t seem to put a dent in.

It’s slowed my play of BMW and I feel really stuck. I’m using the fan to keep him back, but the circular waves he puts out - always mess me up.

Any tips, tricks or W set up’s before I begin the fight would be appreciated!

Thanks
