Nursery rhyme character known as Lille Trille in Denmark

HUMPTYDUMPTY

["This round, egg-shaped figure famously sat on a wall before a great fall and was also mentioned in Lewis Carroll's Through the Looking-Glass."]

This clue refers to Humpty Dumpty, the egg-shaped character from the classic English nursery rhyme. In Denmark, he’s called Lille Trille, a local name for the same figure who famously "had a great fall." The answer is simply the character’s original English name, spelled as one word without spaces.
