You will have to climb a little to get near the pane and throw it off.
Start by climbing onto Trico and reaching one of the ledges above.
In here, there are twobarrelsand it is a good idea to throw them to the beast straight away.
Remain on the ledge where you have found the barrels and head to the opposite end.
Stand by the edge.
Then leap towards the hanging chain and pull up.
Lean back and jump onto the round object.
Jump towards another chain and lower yourself to land on the oblong wooden object.
The platform that you are on is a teeter-totter and it changes its situation under the boy’s weight.
As much as possible.
After that, run towards the other end and jump towards the hanging structure.
Start climbing here by reaching to the edges higher up.
Then, move along one of the walls of the stained glass pane.
You have to reach the hole in the pane shown in screenshot 1.
Cross to the other side of the hole.
Continue up and this time, attempt to reach the hole shown in screenshot 2.
Cross this one also.
Jump over to the hanging object around.
After a while you will reach the very top.
Have him continue the journey.
This way, you will reach a small scaffolding with yet another stained glass pane.

Unmount Trico, make it over onto the scaffolding and shove the pane into the chasm.
After that, call on Trico, jump onto his back and continue the journey.
Trico has to reach the last large pillar.
Here, start to lower yourself carefully over his tail.
After you get to the very bottom, start climbing in the spot shown in the above screenshot.
Make it to as high up a point as possible and start moving along the wall to the left.
