A short door riddle

You fully open the door, then You and Eclipse walk through, You are met by sure enough a sign, you read it,
"H-hEllO! PAls I_ve IGOT ahere a FfRIend HEre TO HElp meE ExplaIN, *Hello My names is not relevant but I will explain a few things, First off your items work a bit differently here. You must find out what each one does because some might do new things you'd never imagine it could do before, If you'd seen the helmet example in the last layer What it could do was float. Each one had a different reaction to certian situations but could still function as properly applied, but on this layer their original function can't be applied anymore, only the courrupted function. But basics will still work, Torch will make light since it has to, Goggles can see otherwise they wouldn't be goggles, and a..book for some reason don't ask me, anyway each item will have a new function here and its your job to find out before you adventure forward, I will give you a few targets to use your items on so good luck figuring it out, and when your ready there will be a door behind this sign that is bright white. The targets will be multi colered so good luck,* GoOD LUCk k FrRiendSS! BYyeE For NowW!"
That's the end of the sign, after looking up you see everything the sign had said,
Where do you go first with Eclipse?
