I think the Banana is Bill Engvall
The kitty has 2 different colored eyes...if you search that Mila Kunis, Elizabeth Berkley and Kate Bosworth pop up...but I think Berkely at 5’ 9 1/2“ is too tall so...? Frog is Morris Day from The Time?
The Skeleton is Paul Shaffer, the band leader from Late Night with David Letterman. Trust me. It’s him...listen to him and watch his mannerisms. My radio DJ husband since 1975 agrees with me. You’re welcome.
