This may be a little late for the young ones going back to school, but it's so good that your Projectionist — who is also an Esperantist — couldn't resist.
Produced by the generous folks at Lausanne, Switzerland–based DANNIRéalisations, this is a simple short entitled Jojo kaj Bubu en la parko. Yes, it's about two friends — a puppet rabbit (Jojo) and a bear (Bubu) — having a great time at a amusement park.
The Esperanto in this short is easy enough that I'm certain every komencanto (beginner) will get it.
Ĝuu, karaj amikoj! Enjoy, everybody!
Elkoran dankon! Thank you, our good friends in Lausanne!
