The creator of Wallace and Gromit was joined by crowds to launch this year's Gromit Unleashed trail.
Fans of the Aardman characters will be able to visit the sculptures in 53 locations in and around Bristol from Monday.
The trail will raise money for The Grand Appeal, which supports Bristol Children's Hospital by funding research, supporting families and paying for life-saving equipment. Previous Gromit Unleashed trails raised more than £20m.
Nick Park, the creator of Wallace and Gromit, said: "People have worked so hard on the designs and decoration of these characters. It's just going to light up Bristol for the summer."
