This phone is too cute! With an incoming call, Pluto barks and whimpers.
Pluto "chews" the handset, then rolls his eyes when the handset is lifted.

Mickey Mouse, Minnie Mouse, Goofy, and Donald Duck all say different phrases in their authentic character voices when the phone rings:

Mickey: "Hiya Pluto! Some day huh? Get your leash ready, I'm almost home."
Donald Duck: "Pluto, where's Mickey? (bark, bark) I said, where's Mickey?"
Goofy: "Garsh Mickey, you sound a little hoarse. I better call back when you're feeling better."
Minnie: "Pluto, is that you? I'm sorry, I can't understand you with your mouth full."
Donald Duck: "Pluto, what's the big idea? What? I can't understand a word you're saying."
Goofy: "Mickey, is that you? Garsh, I can hardly understand you."
