The humorous ad, created by Mother, once again sees Johnny Vegas and Monkey on a hill, having a picnic.
As Vegas struggles to find words to describe how fresh the PG Tips Special Moments range tastes, an exasperated Monkey is whisked away by a swooping eagle and is dropped into its nest, which contains two baby eaglets and the four variants from the range.
After befriending the eaglets, Monkey enjoys his own "special moment" with the baby birds, as he introduces and sings 'The Special Moments range' in unison with the eaglets.
The TV ad will be supported by print and radio, customer marketing and a heavyweight sampling campaign.
Silvia Grattieri, PG Tips brand manager at Unilever UK, commented: "The launch of the Special Moments range from PG Tips is one of the most significant innovations in black tea in recent years.
"The TV advert will help to communicate how the range offers consumers high-quality, fresh-tasting products and greater choice within black tea, to suit different moments and needs throughout the day."
PG Tips launched the original 'The Fresh One' ad campaign in May last year.
