Just a word of warning: Never take your grandchildren to the pet store without (additional) adult supervision. Their pleading eyes and heartfelt promises to feed and clean will cajole you into buying the adorably cute and cuddly little brown Bunny Brothers (and all their accessories). Even if you've never owned a bunny before and are absolutely clueless about the bunny kingdom.
Even if you made an oath that farm animals would never sit on your living room furniture. (Please note that these Bunny Brothers have promptly manipulated their way into the seat of honor. ) Even if you swore you would never intentionally on purpose have rodents with large teeth in your lovely home.
In short order, they stealthily charm their way into power. The King of the Castle is at their mercy. Chaos reigns. The Bunny Brothers have conquered another hapless and naive family.
