From the Super Mario Wiki
Pierre is a Squeek thief in Paper Mario: The Thousand-Year Door who hangs out in front of Ishnail's house. According to Goombella, he's "busting his tail to catch the eye of Ishnail" (and does eventually join the Robbo Gang, though they force him to stop stealing as he does so) and seems to have a lot of free time. The latter is true because, basing on some of his statements, he was once an archaeologist before abandoning his partner underground so he could join the Robbos; Mario and friends can actually meet a Squeek eligible for the position of his abandoned partner within Rogueport Sewers. (As a matter of fact, this unnamed Squeek archaeologist does indeed talk of Pierre at times, making it very likely that the two were once in business.) By the end of the game, this Squeek even stated that Pierre had rejoined the archeology team, though Pierre himself made no note of this, still seemingly focusing on affiliation with the Robbo Gang.
- That's Pierre. He sure does seem to have a lot of free time, doesn't he? Word is, he's been busting his tail lately to catch the eye of the crime boss, Ishnail.
