GIANT sea creatures, scientific marvels and street theatre will greet shoppers in Newcastle this weekend.

Sunday is children's day in the city's Winter Festival, from 11am to 4pm, even including a 50ft-long inflatable sperm whale.

There will be marquees around Grey's Monument where children can learn circus skills, join in crafts, or watch a puppet show.

The Life Science Centre in Times Square will host a luminarium - an inflatable attraction of colour and light.
