The trailer for the second series of an all-access documentary into what life's really like for Chester Zoo's extensive animal population has dropped – and it looks like fans of the popular show are in for another wild ride.

The Secret Life of the Zoo makes a welcome return to the small screen on Thursday (November 17), but Channel 4 has kindly whet the viewing public's appetites by revealing a taste of what's to come.

A toppling tortoise who's not so steady on his feet, a face-palming chimp and an Orangutan family sharing a sweet moment all feature in the sneak peak.

Upcoming episodes will go further behind the scenes than the first series – which was a ratings hit – managed, thanks to even more cameras in even more places.

The first episode will air at 8pm.
