I just saw that. Bean gets smashed in MFS, and on the commentary, Rizzo burst out laughing and said "I love it when the rabbit gets smushed." Then when he slides down, Rizzo yells "Yeah! You deserved it, ya little rabbit."
Which is a little weird, because both are Steve Whitmire...odd...of course Rizzo also disregarded Steve's cameo by yelling "What a freako" so I think Rizzo just doesn't like Steve, nor his characters, in general.
