I had made up a heap, and I was sure I had them one of my USBs, but they're not there... And I can't be bothered setting up my old computer to get to the powerpoint, so I'll just try and describe them from the top of my head as best I can.

An ice cave/temple boss set in the middle of a pool of water, on a slab of ice in the middle of the arena. Around it are other little platforms of ice, which you need to use to get around and avoid it's attacks. It's impossible to reach the boss, normally, from these platforms. The platforms sometimes drift apart, so it's important to take note of the distance of the other platform before leaping at it, as landing in the water turns you into a block of ice, taking consistent damage until you manage to knock into one of the platforms, which breaks the ice and allows you to quickly scramble up onto the platform. Much like the Great Bay Temple boss, getting into the water generally leads to defeat unless you're lucky, as you're more vulnerable to attacks.
The strategy is to avoid it's attacks and get to him. This requires the use of the megaton hammer (acquired in this ice temple). His attack pattern differs slightly after you hit him a few times, but generally he'll:
- throw ice crystals at you: possible to avoid without leaving the platform, but generally it's safer to jump onto another anyway, unless it's too far away
- throw an entire platform: just jump to another platform to avoid it
- breathe a stream of icy wind
The last is the most important. When he does this, in order to be able to get to him, you need to take advantage of it - timing is crucial. When he does this, stay where you are and use the megaton hammer, timing it right, to get the platform to sink slightly, then bob up. As it does this, if you timed it right, his 'breath' will turn to ice and connect with the platform. Jump on it and slide down (balance is basically automatic, just don't move the control stick left or right, predictably), and then attack. It's really up to you what approach you take, but the sword is safer, as the megaton hammer is slow and can cause you to be knocked back slightly. Once you've had a fair share of attacks, the part of his 'island' you're standing on will break off and join the circle of platforms. Repeat this two more times, minimum, to pass the first stage. The movement of the water speeds up during these, and so does his attacks.
The second stage has him coming at you, finally free from being stuck to the island. Basically, you run, avoid ice crystals, and when you think it's a good time to do so, use the megaton hammer to have him smack into an island. When he falls into the water, a little platform of ice emerges around him, enabling you to get close and have more strikes. Repeat this at least once to clear the boss.

Okay there's one. Might do the other one later... >_<
