There's no way those things are from our planet/dimension and I doubt Shredder would've used mutagen on ordinary worms for that...or that he's anticipate them coming out the way they did. Um dude, you clearly haven't seen Clash of the Mutanimals. Baxter Stockman was seen creating them by using mutagen and a mind control serum on normal earthworms to turn normal earthworms into brain worms. Their origin has already been witnessed. Come on man, I thought you were the insider xD

Dude, I don't know what channel you were watching alongside Nickelodeon on the morning of May 3 (2015), but there was no scene showing Baxter using mutagen on those worms. All we saw was him dipping the worms in that serum. No origin (full at least) was ever witnessed!
