Firstly--I realize you're new, but there's another topic on this model directly below this one in the respective forum. In the future, please use the search function.

87-89 are essentially what's called an Elias stretch. Sara Adams has a great tutorial on her site (Happyfolding) if you're not familiar with those.

Hmm, I thought I remembered seeing one.

I know this model uses a few of them.
All you're really doing for the mammoth, though, is spreading the pleats and creating a pleat at something of a perpendicular to the existing pleats. Steps 88-89 of the diagram are fairly clear about the crease lines, IMO.

To Baltorigamist,
I am talking for step 87 not 88-89

First of, what diagrams are you working with? The ones from Works of Satoshi Kamiya or the ones from Tanteidan Magazine 85? That's an important information as they differ quite a lot.

Assuming you're not having trouble with the simple valley folds from the magazine I guess your problem is opening the front layer and squashing the corner. This is a folding manoeuvre that is split into several steps beginning at step 87 with the end result shown in step 90. It is not possible to see step 87 as a single step on it's own. Look forward to 88 and 89, they show in more detail what you are supposed to do. The result of step 87 is step 90.
