Help! Stuck in England. DS version

[Anyanka]

Hi Everyone.
I would sure appreciate some help. I am playing TRL and am stuck in England. I have swam to the castle and entered via the roof, am in a large room with a bell to my left and what looks like a large gold egg to my right.I can grapple and move the thing haning from the ceiling but don't know what next. Have tried to jump and hang from it but????????????

What am I supposed to do next? Have had no problems till now. Did I miss something in a previous level or outside? Difficulty setting is on Normal.
Am getting fustrated

Thanks.
