The Flibbertys (misspelled here as "The Fibbertys") was a comic strip created by Ray Helle in September 1954, and which ran until 1972. It concerned a family named the Flibbertys, consisting of mother and father Fran and Stan, children Wendy, Butch, and Sis, their dog Geddown, and their cat Preston. Geddown and Preston had dialogue balloons, but it didn't mean they could "talk." Any dialogue they had could only be understood by other animals, and not any of the human characters. Unlike a character like Snoopy or Garfield, these were not thought bubbles, but actual dialogue balloons, so it makes you imagine that they are actually speaking, just in a different language perhaps.
I find it interesting that in this strip the parents are looking for where the kids hid the presents, when usually it's the other way around. I think Butch has the right idea, too. You should set booby traps in your hiding places, especially if you can't find anywhere good and all of the places that are available are the really obvious ones.
