I can't believe this show acknowledged A Pup Named Scooby Doo as canon

I just recently discovered that one of the episodes had Velma having a flashback to a birthday party when she was a kid and the flashback is animated so they're drawn to appear how they did in A Pup Named Scooby Doo. Ok WTF? A Pup Named Scooby Doo does NOT work in the *beep* Scooby Doo canon you idiots! Its a freakin' parody with cartoonish antics and isn't meant to be taken seriously whatsoever. There is no way that A Pup Named Scooby Doo can fit in the same continuity as "Scooby Doo, Where Are You?" and "What's New Scooby Doo" because it has a totally different tone and it is meant to be a joke more or less. I don't have a problem with a Pup Named Scooby Doo, it does its job well, but how can people seriously expect this show to be in the same continuity as the more serious shows where the gang are adults. It doesn't work, plain and simple. Stop acknowledging a god damn joke show as a legit entry into the Scooby Doo universe when it is nothing more but a parody. That show needs to be ignored and shouldn't be mixed into the more serious "What's New Scooby Doo". Seriously, fans and animators can be so damn stupid at time. Don't acknowledge a joke parody show just because it is in the same mythos.
