I would say "Clawgrip" ("Clawglip" sounds like Engrish, with the R and L confusion).
"Triclyde" is probably in reference to the three heads ("tri" meaning "three", after all), though I may have spelled it "Tryclyde" myself a few times.
I thought this was about the Ostro/Birdo confusion in the manual...though I guess Birdo's appearance in later games clears things up.
