Is it possible this is the 2004 TV series, Shoebox Zoo?
Shoebox Zoo mixes Scottish, Celtic, and later, Native American mythology. The first season is set primarily in Edinburgh and other historic locations, while the second season moves to Denver, Colorado, though the season was shot in Canada. The series' protagonist, Marnie McBride, an eleven-year old Scottish-American girl moves to Edinburgh with her father Ross following the unexpected death of her mother Rosemary. On her birthday, Marnie receives a shoebox containing four carved toy animals from a junk shop owner. Marnie discovers she can magically bring the toys to life, referred to collectively as the Shoebox Zoo. The four are in fact humans transformed into toys by their master, Michael Scot, an immortal alchemist and wizard, for stealing his magical codex, the Book of Forbidden Knowledge.
In the series' backstory, Michael Scot lived in 12th century Scotland, where he crafted the Book of Forbidden Knowledge, containing his scholary work on alchemy and magic. However, the book contained black magic forged from Michael's pride and ambition. He created the series' antagonist, Juan Roberto Montoya de Toledo, a shapeshifting homunculus, using the book's magic. However, Toledo was rejected by Michael, inspiring him to seize the book's power and conquer the world. Michael's four students - Edwin, Bruno, Ailsa, and his own son Wolfgang - steal the book to hide it from Toledo, though Wolfang takes it out of spite towards his negligent father. The book is lost, Michael transforming the four into toys and putting them to sleep until a prophesied Chosen One, identified as Marnie, possesses magic to awaken them and find the book.
One of the toys is indeed snake-based:
The Shoebox Zoo themselves are four computer-generated Celtic toy animals, actually Michael's students transformed into toys for stealing the book. The voice actors recorded their lines in a London studio before filming for the television series began. Edwin (Rik Mayall), a silver eagle dressed like a knight acts as the self-appointed leader, but he is pompous, vain, hypocritical and cowardly. His name and inability to fly is a nod to British Olympic skier Eddie "The Eagle" Edwards. Bruno (Alan Cumming) is a kindhearted but bumbling, dim-witted bear made of stone and fascinated by the modern world in counterbalance to the others' fear of it. Ailsa (Siobhan Redmond), a cynical, distrusting golden adder is the sole female of the group who has little faith in others. The fourth member is Wolfgang (Simon Callow), a wily and deceitful blue-and-golden wolf made of wood, is Michael's bitter son, and joins forces with Toledo during the first season.
From the intro for the first episode, your elevens:
In every generation dawns a most auspicious day, the day when four elevens meet, and sleepers have their say. The day to which the fickle sands of time and tide have run. The day when fate and prophecy, reveal the chosen one.
Marnie McBride was 11 years old, that's to say at precisely 11:00 that
evening the eleventh day of the eleventh month she would be 11 years old.
My final search terms which found it was tv film animal statues come to life at 11:11 after several abortive attempts at looking for "11:11:11", which largely points to a few horror films using that as a date.
You can find episodes on Youtube, but I haven't found anything official.
