Crawdad Mike is Tour guide of New Orleans. He and his driver give tours to visitors of the town and usually throught the cemetary. When Scooby and the gang were frightened by the Leland Brothers' ghosts, Mike and his driver got them away to safety and explained to them about their past before droping them off outside the Leland Hotel.
Later the gang met up with him to ask him questions about the gunk on Daphne's show and said it was ectoplasm.
After the Leland Brother's ghosts were subdued by Scooby and the gang, Crawdad and his driver were exposed as the culprits under the masks as Velma suspected judging by their height.
- Crawdad Mike was voiced by Jim Cummings who also voiced Cyrus Buford in Big Scare in the Big Easy.
