What is this advertisment?

[Lem Lou123]

While holidaying in Lanzarote July 2011, I came across this advert numerous times: There are around 7 or 8 children larking in a farm picking strawbewrries with a questionable old man. They were all eating strawberries and the eventually made them into strawberry yogurt. There was also a lady commentating in the Spanish native tongue. Could someone please tell me what this was an advertisment for? (It was probably also aired in Spain and other Spanish speaking countries) Thanks!
