Help - starry night step 84

I need help with step 84 of starry night on page 189 of the guidebook. As I built it, I have a piece in the way of adding the new piece in step 84 and don’t have a way to click it in. Did anyone encounter this or do you know what I did wrong? Thank you!

Now that new Storm CMF is out, I finally understand LEGO capes, updating Batman next

Change the snow to dirt?

Where could we buy pieces exactly like the white ones on this "ramp" and change the snow to dirt? We aren't so much the skier type, my hubby is all about the mountain biking though! So we want to make this like a mountain bike track instead. It's the Lego city ski and climb set.

First time seriously obsessing over a Lego set

A fine addition to my collection

Why did my instructions come fresh out the box with a gigantic stain and mound of dust in them? This is really disgusting.
