How do you get to the kid with gohts mask on in the mini temple in majoras mask?

In this mini-temple it's required to use Goron Link's curling technique to curl your way towards the kid with Gohts remain on.

Bounce off the treasure chests to steer yourself around the temple until you reach an area where a frozen platform and a door is. Back up as much as possible and curl your way towards the door to jump your way too it.

Inside you will find the kid and he will ask for two more masks.
