Fighting Pap with less than 4k HP

Not really. If you can't take a hit from the bottom bombs, it doesn't mean you can't take a pap touch.

About how to kill without taking bomb damage. All I can say is dodge the best you can. You could try recoiling INTO pap to take touch instead of bomb damage, but that'll be a bit difficult.

I can KB it with an Apple, or by using Torpedo/Homing/lolAir Strike. I can take touch damage just fine, it's just really hard to make sure I dodge the bombs. And I don't want to use an Apple before bombs max out.

Anyway, I'm going to attempt it again right now.

I'd be screwed if i got cornered. It's not a nice place to be.

Just like the pics you posted, I think second body is almost impossible if you can't kb it. If it flies under you, you're pretty much screwed..

First body is obviously capable if you can survive Pap's touch damage. If you hesistate when it spawns its bombs, you could Dash into it for the 2k touch instead of trying to time your Recoil to get away from it.

This, basically. The KB goes for both first and second body, and not even kevin (rejang) can KB him and he's like 7 levels above you. I hate dealing with second form unless i constantly KB it, so just max cannon and then go.
