This trophy seems difficult and tedious at first, but it actually comes pretty quickly towards the end of the game and you shouldn't need to play through challenge mode more than once. And that's even after buying all the mega weapons and RY3NO.

* Annihilation Nation is a great place to rack up lots of bolts early on
* Get all the sewer crystals, it's easy money
* Don't skip the Qwark vid comics! You can get a quarter of a million bolts by getting all or most of the tokens and completing the level quickly
* Do the jumping wrench smash frequently, all those little bits of bolts from breakables add up quickly
* Go through Zeldrin Starport a few times, lots of stuff to smash and enemies to kill pretty easily and quickly
* Go through the second Obani moon several times, can usually get around a million bolts if you keep your multiplier up
* Go through the Koros BFG base several times as well, tons of stuff to smash

I got 5 or 6 million bolts in 30~45 minutes by going through Koros, the last level (name escapes me at the moment), second Obani moon, and through that cycle once more.

The jump down from the chair is a good idea, but if you can't do it, try using your charge boots. Aim yourself at one of the ramps and as Skrunch runs towards you, double tap r1 , and launch yourself past him, but only by a little. While he starts to run in the direction your going, he can't turn around until he resumes normal pace, so you have a second were he's running alongside you. This is how i got mine, it involves the same timing as jumping from the chair, but you can see Skrunch the whole time.

This is very similar to the "explode all the underwater crates" trophy in RC1, but much easier as there are only two short linear sections to swim through.

This is probably easiest on the first gauntlet. Just time your jumps so that you're not burned and keep your gun out to take care of any enemies that come your way before they're too close. If there's a lot there then just some crowd control and throw a few bombs their way just to be sure. If you feel you're not good enough try it again with the Shield Barrier and / or Mr. Zurkon. Don't rush anything and you should get this no bother.

For this one, the enemies in the walking tanks become your friend. If you have the Refracter equipped, their lasers will be reflected back at any target you aim at. Just try to leave the tanks alive for as long as possible and clear out the rest of the enemies. Remember though, that the Refracter won't protect you from other attacks. I found the first Aridia mission the easiest place to get this skill point. Must be done in one life.

The Snowman Skin is obtained through the Skins section of the Specials menu when you press Start. It costs 4 titanium bolts to unlock. It shouldn't take you too long to get 4 bolts. If you need help just look up some of their locations on YouTube and this will be yours in no time.
