Trials Fusion

[0:09] - Bottom Dweller
After the 3rd checkpoint, you'll use jump down onto a ramp and you'll need to bail near the top in order to have your character to grab a red valve connected to a pipe overhead. Once you're holding on, use the Left Stick and hold Right to turn the valve, which will spray water over a fire later on in the level. Now progress to this part of the level, and instead of following the track, go under the pipe and you should land in a cave/tunnel. At the bottom, reverse up to the dynamite controls, and press down to explode the wall. Move forward to reveal the squirrel.
[1:42] - Deeper Underground
This takes place in the first person maze. It is recommended that you watch the video as it can be quite disorienting and difficult to understand via text. Progress through the maze until the final area where you see the 3 pylons with a bush behind them. Instead of dropping down, turn around and go through the gate on the other side of the hall. Proceed through that gate until you end up in the large open room with all the boxes again. Instead of going overhead, as we did before, go forward into the hall. You'll notice all the doors are locked in this hall. Walk up to the far door on the left (it's locked), then move back to the middle of the hallway, wait for a few seconds, and return to the door which should now be opened. Go to the back of the room, and the wall will move to reveal a secret tunnel. Find the squirrel at the end of the tunnel.

Proceed to the part where you use metal grate ramps with lava following underneath them. Make your way halfway to the top of this section. Now, you'll need to gain some speed, go near the top of this part, and bail backwards. As you are flying backwards, you'll notice a hanging chain that you will need to grab onto. Hold onto the chain until it moves and a cinematic starts to reveal the final squirrel.

Bottom Dweller

First of you wanna grab the drain pipe handle thing until the second screen appears. Once that appears hold right on the until all 3 red things pop out of the pipe, you'll see the short cut-scene and then be put back on your bike.
Continue through the track until you see where i go underneath the proper driving line. Pop down there and when you get to the bottom make sure you don't hit the explosives. Back up to the detonator and hold down on the to make the explosives go boom, once the walls broken drive forward carefully (because you can't see your rider). Once you enter that room you should get the squirrel.



Deeper Underground

I've skipped the riding of the track at the start of this video, it starts at the same point as the "Curiosity Killed the Cat" achievement, so if you don't know where it is just watch the start of that to get a reference point.

So this one is really long winded and gonna be confusing to explain in words, so I won't be doing that, there's only one part I think needs explaining.
At around 2:11 when I walk up to the door and turn around and walk back, you have to do this to get the door to open. You should hear it opening behind you and then you can go through.



Iron Incendiary

For this one you wanna drive through the track until you get to the part with the lava drain things that you drive up. Go up the first one and get the checkpoint that's there. Now you'll want to drive to the top of the next ramp and keep as much speed as possible, once at the top bail out and hold backwards while stil holding to grab onto the chain above.
You'll see in the video that I drop whilst on the chain, it wouldn't move for me so I tried to get closer to the bottom and see if that worked. It didn't work, so what I did was just wiggle the and it started to move.

Also there's about a minute long cut-scene after the squirrel that's pretty funny as well and well worth watching it.
