It can be ignored as in no need to watch it, but not avoidable. It was one of the first scenes in and will be references a small amount of times. Not the most ideal thing I implemented in hindsight, but it is how it is.
As per description up above:
"The Thighjob Scene follows next. And it requires to have viewed the Bodyjob Scene, to have discovered the Second Firewall and to have saved or attempted to save Gomamon at every Digimon encounter. Not to mention a large blue good bar."
I am unsure what condition you haven't fulfilled honestly. It sounds like you should have it. Did you click a few times on the main site with the "..." to activate the scene?
