While playing in Doc's room, Stuffy hears a strange sound coming from Doc's toy box as it was a toy cell phone named Loud Louie who Doc got on the same day she got Lambie as Louie talked in a very loud voice as he tries hard to talk quietly.

Loud Loud Louie
Toys that debut in this episode: Louie
It is revealed that Doc got both Lambie and Louie on the same birthday.
Lambie: Hey, you got this phone on the same birthday you got me. Wasn't his name Louie? Doc: Wow, good memory.
Louie: (to Doc) Remember when you pretended to call the ice cream truck? Doc: I'll have a quadruple duple scoop of razzle berry ripple, please. (Both Doc and Louie laugh) Stuffy: Mmm. Sounds good to me.
Hallie: (to Louie) Why, you're more excited than a puppy on a play date. Chilly: I'll say, and loud too! Do you think I could get some ear plugs? Doc: Sorry Chilly. Snowmen don't really have ears to put the ear plugs in. Chilly: Who knew? (Doc giggles) Oh, you did. You knew. Thanks Doc.
Doc: Sometimes we need to observe out patients to figure out what's wrong with them. Stuffy: We should totally observe our patient. It won't hurt the little guy too much, will it? Doc: No, Stuffy. Observing Louie means we watch him to see why he can't talk quietly.
Lambie: Louie, you're supposed to (whispering) whisper. Hallie: If that was a whisper, I'm a purple hippo. Stuffy: Um, Hallie, you are a purple hippo. Hallie: Oh you know what I mean.
Differences Between Episode and Book
Lambie was on two legs the whole time in the book, although in the episode, she was in all fours in some scenes.
