Peter regards his late father this way, using his old journal to learn how to become a clever and brave young" rabbit.
The Plum Thief from the same-titled episode, AKA Peter's Mother.
Adaptation Personality Change: A fair few examples. Benjamin in particular. In the novels, he was about the same age as Peter and even more headstrong, dragging him back to Mc Gregor's garden somewhat against his will. In the series, he is noticeably younger, and is Peter'sCowardly Sidekick.
Adaptational Badass: In the original novel, Peter, while still managing to escape Mc Gregor, was more of a Miles GloriosusBratty Half-Pint left a wreck by the whole ordeal, his capability only starting to truly show in his final appearance as an adult. In the series he is an adventurer who tackles Mc Gregor and other threats on a regular basis.
Dr. Jerk: Dr. Bobtail is a Downplayed version: his sternness generally stems from understandable concern about their activities, to the point where he considered moving away for Lily's sake.
Everybody Knew Already: In "The Tale of the Dash in the Dark," Benjamin spends most of the story trying to hide the fact that he's afraid of the dark from Peter and Lily, only for him to finally say that he has something to tell them and them to say "You're afraid of the dark?"
Expressive Ears: Seen on occasion. In "The Tale of the Angry Cat," when Peter tells Cottontail that it's way too dangerous for him to catapult her into Mr. McGregor's garden, her ears droop straight down and she cries.
Humans Are Cthulhu: Mr McGregor is feared by all the animals, though that doesn't stop them from constantly raiding his garden for goodies.
I Always Wanted to Say That: Benjamin with "Let's hop to it!" in "Benjamin's Strawberry Raid." He starts to say it again, then stops himself, seeming to realize that saying it a second time just kills the impact.
The Moving Experience: In one episode, Dr. Bobtail considers moving to get Lily away from her friends' bad influences. To try and convince them otherwise, Peter and Benjamin try holding a picnic and being on their best behavior... while trying to keep the predators from crashing it.
Or So I Heard: Benjamin says this when Peter's sister Cottontail is having trouble sleeping and he says that nightlights are good for helping little kids to get to sleep.
Pantsless Males, Fully-Dressed Females: Peter has his familiar blue jacket, while Benjamin has a knit cap and darker jacket. Lily, Peter's mother, and his sisters all wear dresses that cover significantly more of their bodies.
Rummage Fail: It tends to take a few tries to pull something out of the Just-In-Case pocket that's relevant, and Lily doesn't always recognize what'll come in handy herself. Lampshaded in "The Tale of Benjamin's Strawberry Raid", where she comments that she really needs to organize it sometime.
Super-Persistent Predator: Mr. Tod treads the line, as he's generally willing to pursue the main trio yet again regardless of how many times he's failed. The same goes for Old Brown.
Survival Mantra: When Benjamin is scared, he likes to remind himself that "Rabbits are brave, rabbits are brave, rabbits are brave..."
