I tried to write all the Frozen characters and none of them work - also, his name is Kristoff, not Christopher. Also, for the Valentine's question, could it accept different formats for the date? like 14 Feb, 14 February, February 14, etc. and for the thermostat question, could the word 'temperature' be accepted on its own? And the Jack and Jill question, could it be accepted as half the sentence (i.e. without the words 'they went' or with only the words 'pail of water')?
