Robi will usually not appear unless an exterminator has been hired, but, like other service NPCs, he may occasionally appear at community lots. Robi has the same facial structure as Jonathan Ternynck from Veronaville. In Pleasantview, he will always have the personality points, skills, and interests shown below. However, they are always randomized when he is generated in custom neighborhoods. Sometimes if Robi is made playable, his PlumbBob will be inside him, instead of above his head. This happens with several other NPCs in The Sims 2.
