Issues with Bowser's 'Cool' Fireballs and Skewers

[Arco]

I am in development of a winter themed Mario level where the final boss consists of a boss battle against a reskinned and reconfigured SMB 3 Bowser to be an Ice version of Dry Bowser. The boss consists of an ice brick floor for Bowser to smash through and skewers lining the walls. I have two issues that I would like to know if it is possible to resolve.

1. Is it possible to use LunaLua to have the skewers either simply push Bowser and/or not do damage to him? How would I go about doing this?

2. Dry Bowser's 'Fireballs' are now Ice, and I wish to make player fireballs snuff out any they hit, how could I go about doing this with LunaLua?

Side notes: I have played around with the NPC configurations a bit, and through trial and error, it is not possible to do these tasks with the configurations alone. I am using SMB X 2 (2.0.0 b4). Thank you.

EDIT: My apologies, I put this in the wrong section, I should have put this in the LunaLua help.
