Does this count as modern art?

Mariel enjoyed her first week of kindergarten and was very happy to go back this morning.  She literally ran down the block to get to school.
She must have seen a puppet show or learned something about plays, because she spent most of the evening staging shows in our front room.  While some of the plays were very understandable and reasonably scripted...

Mariel: DAD.  This is going to be a grandmother and a granddaughter.
Dad: OK
(Scene begins)
Barbie 1: Hi! I am the grandmother.
Barbie 2: Hi Grandmother.  I am the granddaughter.

....others were a bit different:

Mariel: Is everyone ready?
Mom, Holden, Noella, Noella's baby doll, and Dad, all sitting in the audience: Yes!
Mariel: OK
(tiny stuffed pig rises over the back of a chair)
Pig: OINK.  oink oink. OINKY.  oink. (this continues for some time)
(tiny pig disappears, large stuffed frog purse appears)
Frog: Ribbet.  Ribbet.  RIBBET RIBBET. (and so on)
(Frog disappears to subdued laughter from the audience.  Tiny blue fairy appears)
Fairy: I am a fairy. I sit (fairy falls off the chair, reappears).  LA LA LA.
(fairy flies away.  pig emerges briefly, then disappears)
Pig: Oink! oink.

We are undecided as reviewers.  Is this modern art?  Avant garde? Or a production in clear need of subtitles?
