Thinking about how Kermit was more interested in adventure as a baby then when he grows up, it's similar to Tommy from Rugrats. As a baby Tommy is very adventurous, but on All Grown Up* he's more interested in filmmaking (and adult Kermit is involved in the entertainment industry). Wow, Kermit and Tommy have so much in common...
*I haven't watched that so too often, so I could be wrong about the lack of an adventurous personality.
