KIDS TRIVIA

Detailed explanation-1: -When Harry Potter is having difficulty figuring out a way to complete the second task of the Triwizard Tournament (which requires him to rescue Ron from the bottom of a lake), Dobby steals some Gillyweed from Professor Snape’s store cupboard and gives it to Harry to use.

Detailed explanation-2: -Harry Potter used Gillyweed during the Second Task of the 1994 Triwizard Tournament. Dobby gave it to him, after overhearing a conversation which Barty Crouch Jr., disguised as Alastor Moody, staged with Professor McGonagall.

Detailed explanation-3: -Snape will get no such treatment from Voldemort, no matter how useful he might be. Dobby finds Harry in the library and gives him gillyweed, which enables him to grow gills and swim easily underwater. The route by which Harry gets the gillyweed is a little circuitous.

Detailed explanation-4: -So Dobby steals gillyweed from Professor Snape’s private stores to allow Harry to breathe underwater during the second task. (Later on, we find out that Moody engineered all of this in order to make sure Harry wins the second task.

Detailed explanation-5: -In GoF, the movie, it’s Neville who gives Harry gillyweed, and later on we find out it was stolen from Snape’s storage. Imagine how brave Neville had to be to steal from Snape, his greatest fear (as seen in PoA). That was just a great detail, really values the beginning of Neville’s maturing arc.
