Watership Down (1999)

Season 2: Episode 3

Kehaar becomes homesick of the Big Water and decides he must go and visit it, with the rabbits tagging along too. Smelling the glorious smell of carrots and lettuce, the rabbits wander inside a big farm van to nibble at the food. Suddenly the van drives off, and the rabbits find themselves at a market where they make friends with a pig.
