Biker Thug: We don't like your kind around here

Sonic: Our kind? what kind is that?

Biker Thug: Hipsters

Sonic: *gasp* How dare you?

Was Sonic mad because he called him a hipster, or is sonic insulted from the way they are respecting hipsters (being not at all)?

The Safe Worlds Map has many planets that don't actually appear the film, however, Sonic already has them crossed out, either implying that he had visited them, or knew about them in some way already.

Of the planets shown, 6 are unknown. One is almost entirely crossed out, making it very difficult to tell what it could possibly be. The one to its right is a spherical blank texture planet, seemingly a reference to the special stages from Sonic the Hedgehog 3, yet it's odd that that would exist within the same universe. At the bottom, a planet with a star shape is present, with a similar look to bumpers and symbols from the classic series. The planet to its left is very difficult to make out, some sort of triangular shape atop a sphere connected to outer planets. Closest thing I could think of would be Eggmanland from Sonic Colors, but that should be impossible given what we know. A planet wrapped in a pipe is at the top, which I assume is a reference to the Sonic the Hedgehog 2 special stages, a winding half-pipe. Then there's the sun shaped planet with a face. I don't believe this is a reference to anything within the series, so what could it be?

Update: The pipe-rounded planet is a reference to the SEGA Saturn; still curious of what it looks like in-universe.
