Detailed explanation of unlocking conditions of Halloween letters in animal restaurants
4 yellow+gold +4 blue; Otter (t m) 2 formula: iron +4 blue +3 white; Egg 5 can't fly and can be bought from black merchants (originally obtained through Halloween parties); Egg 6:3 yellow+copper+1 maple (you can try other grades, as long as you don't leave this formula)
To unlock the little fox, you need to fly the little fox diary 1 first, and the formula is yellow iron. Unlocking the little fox requires flower arrangement: yellow+red+blue. Arrange flowers at the end of work, and switch to garden promotion+video promotion, which is better with wandering singers. Why do you want to go to the garden for publicity? Because it is easier for small animals to come over without staring at the restaurant. I hope I can help you!
