The entirety of Mei and Gabu's first meeting is a mixture of this and Heartwarming; a goat and a wolf hiding together and developing a friendship through conversation, not realizing who they're actually speaking to.
The whole scene when Mei and Gabu show themselves to each other. They just stare at each and look completely shocked when they realize who they spent the previous night bonding with. Too bad the remake cut the scene down.
Gabu struggling to contain his hunger during their second meeting. At one point, all he can do is twitch and shake uncontrollably while watching Mei. Fortunately he manages to snap out of it.
