Unauthorized Baggage Car Access Glitch

Let there be hotdogs!
Hello... I have a question about what appears to be a glitch not covered in in the Paper Mario: The Thousand-Year Door glitches page. I was riding the Excess Express to Poshley Heights after Chapter 6 when I somehow slipped past the conductor and got into the baggage car. When I climbed onto the roof and used Tattle with Goombella, she appeared to still be programmed to see the smorgs there. I can't seem to repeat this glitch.

Any chance anyone knows how this happened?
