what dragon required for last level food quest dragon city

In short, my main question is what are all of the required dragons to complete the cups and can I fulfill them through happy hour? Thank you to anyone who reads this post and answers, while the quests are mostly fodder i do enjoy slowly working my way through them and it's a shame that they have such a steep price just to enjoy them fully.

Huge Food Farm: This is unlocked at Level 18, costs 500,000 Gold and earns 250,000 EXP. Big Food Farm: This is unlocked at Level 8, costs 25,000 Gold and earns 25,000 EXP. Unfortunately try as I have to find one definitive post that states requirements to complete all of the cups, alas I have come up short and focused on summoning another legendary: Drathic. Food Farm:: This is unlocked at Level 1, costs 100 Gold and earns 100 EXP.

In other posts that feature the quests there have been comments that mention required dragons to pass and so with this happy hour I would like to take this opportunity to just summon them.

I gave in and got the dragon which I justified in that I want to complete all of the cups however it got me thinking. I've hit the point in the quests that they require you to have a legacy dragon which was virtually impossible without high f2p until that little pop up a few days ago.
