Don't see why they wouldn't. He is a pretty active voice actor, especially in Nickelodeon shows like Fairly Odd Parents and Spongebob.
Though they didn't get him to reprise his role for the Hidden Temple "The Splat" disclaimer. They just used the guy that's the voice of the Nicktoons channel.
Actually, on the subject of the Splat disclaimers, I love what they did with them. Many a fan eye rolled at Sesame Street Old School's "not for kids" disclaimer, and the WB released Saturday Morning DVD compilation sort of made sense because of the mild language on the bonus features, I guess... I'm guessing Viacom forced them to make one for the block, and they just ran full on passive aggressive with it. The message goes from "this is intended for adults" to "you know what? You probably wouldn't like it anyway because it's not Sam and Cat." Not in those exact words, but the intention is there. Making these funnier than they need to be and getting some old favorite cast members back in the process to do it.
