We're lucky, as Nick Jr bloggers we have already had a sneaky peak of this, but nothing quite beats seeing it on the TV!
The magical three part special is a tale of elves, fairies and unicorns, with Dora and Diego on an exciting quest to restore calm and happiness to the Enchanted Forest.
The adventure starts today at 4.30 pm on Nick Jr with 'The Tale of the Unicorn King' (Sky 615, Virgin 715 and TalkTalk 318). It continues tomorrow at 4.30 with 'the Secret of Atlantis' and then concludes with an exciting hour-long special on Thursday at 4.30 called 'Dora saves King Unicornio'.
The full trilogy is also repeated on Nick Jr:
Friday 11 November at 4.30pm

Sunday 13 November at 12pm and 3pm
Saturday 19 November at 1pm
