Jingle needs help!

It is Christmas Eve morning and everyone is getting very excited for the big day! 

Everyone except for one little elf called Jingle.

Jingle is in a panic! It is her job to look after the reindeer and she has lost a very important key!  The key that unlocks the cupboard that contains the magic reindeer food!  This is the food that makes the reindeer fly.  If they don't eat it soon they won't be able to pull the sleigh!

Poor Jingle, she really needs your help!
