Dinovember is an annual project from husband and wife Refe and Susan Tuma.
The premise is simple. For the month of November, the family's dinosaur collection comes alive.
Their kids are convinced it's real.
The project began last year, Refe tells BuzzFeed.
The pair have four children, aged between 6 years and one month old.
The set-ups are complex, from this cardboard castle, complete with tin-foil armour and weaponry.
To the zipline that they built in their living room.
Refe and Susan encourage other dino-enthusiasts to join in via the Dinovember Facebook page.
