Baby Bear really didn't improve as a character until Season 30 when they better solidified he and Telly as a duo, otherwise, prior to that, his whole character was a little more than a constant crybaby over Goldilocks, which just got so old and tired after a while.
Similarly, Zoe worked better when she was paired up with Elmo - especially whenever Rocco was involved, because it brought an entirely different dynamic to their rapport by having Elmo be the straightman constantly flustered and frustrated by Zoe treating Rocco like a living pet.
