The VG Resource

Hello, I am trying to get sprites from the discontinued game called Car Town Streets. Some png files are normal png files but most of the files have this odd header. I searched it and it said it was WEBP so I renamed it to WEBP and still wasn't openable. What is this?
Note that this is not a normal png file it is a fake png file

Still lookin help for this.

Doesn't seem like a valid WebP to me. Resolution is supposedly 1025x262145. Ha, nah.

Hmm, it must be a custom format.
