So the event is simplistic, feed your monsters as much as you can. So what is the best way to do it?

I have hit top 50 once before by breeding and feeding Pandaken. I assume this is one of the easier ways to do it although needs a lot of dedication?

Top scorers in the event are over 300 million food which is a lot of breeding and feeding of any monster type.

You have to have mad food and gold to be at the top top but for me I save up. I keep hatching my legendaries I get and don’t feed them much for a couple weeks or more. I do just enough to get my rewards for one or two growth spurt challenges then when the next one comes I use all the food I’ve saved up and feed like 10 or so monsters till level 100. That way I’m not feeding just for the sake of feeding and I get a gems reward. I have 8 legendary monsters rn waiting to be fed around level 10 or so
