Trico has more surprises up its sleeve. You won't be expecting this.
Get the smoking blue pot first
There's a chain here, but you'll need to jump onto it via Trico because of the hook at the bottom, then climb the wooden steps and pull the lever, which prompts Trico to leap up to a pillar above a flaming torch.
When you climb back down, so does Trico. Climb onto it, and wait for it to jump back up to that pillar. From here you can jump to a wooden ledge and follow it around.
You're now in a room with all sorts of oddities. There's a globe that you must first jump to, then to the hanging cage, then over to the wall ledges and down the chain where the blue pot hangs. Pull the lever at the bottom of the room.
This lowers the blue pot giving off those fumes that Trico loves. Take it and carry it up to the top of the steps.
Open the barred doors and drop it down to the floor below, then pick it up and hang it on the chain with the hook that you climbed up earlier. Trico will pull at it, raising the gate in front of you.
Prop open the gate
Run through and pick up the barrel, throwing it in the center of the room. Now pull the wheels up the ramp to the top.
Push the wheels over the side of the platform, where it will stand on end.
Now wait for Trico to pull the gate up a decent height, and push the wheels underneath to brace the gate. Now you can call Trico and he'll come in to eat the barrel.
How to pass the stain-glass eyes
Mount Trico and jump up to the next level, where you'll be faced with two stain-glass eyes staring at each other. Trico will not cross this path out of fear, but it does lay weird jelly eggs. You'll have to go behind it and look in the green grass.
Pick up the eggs and throw them at the eyes to break them, allowing Trico across and up to the next level and back outside.
