Yes, Noel McNeal, who plays Bear, also played Magellan the Dragon on Eureeka's Castle. Also, Pam Arciero (Grungetta on Sesame Street) played Quagmire and Emma; James Kroupa (Otto on Bear in the Big Blue House) was Batly, Sir Klank, and the Giant; and Brian Muehl (did various incidental characters in assorted Muppet productions) was Bogge and Mr. Knack. With all these Muppet performers on it, it's surprising that Henson WASN'T involved with this show. Guess the secondary puppeteers are allowed to moonlight...
