I had some time looking for this error in the forums, but looks like I'm the first one with this thing. I'll do a complete report.
I don't want exactly to use Birdo in my hack, it was just a test. I've set the sprites.txt file this way:

Extra Info: 2
Okay... It appeared as a grey Spiny, and Lunar Magic said it was a Buzzy Beetle... Then, I put Birdo's ExGFX as 80. I changed SP4 to 80. It became something that looked like a hedgehog in Lunar Magic. No problems until now.

This black birdo appeared... and, it couldn't hurt me, I could jump on him, get trough him, all he did was to be always facing me...
Report complete. Can anyone help me?
