Hi there, I need a particular critter to finish my quest if I am freeze does it count anyway or I have to have my garden unfreeze?
If you need to spot a particular critter for a quest, I believe you can do so even if your garden is frozen.
Obviously, your garden needs to be thawed for the attracting portion of any quest.
How can I attract 2 different zodiac creatures when only 1 zodiac plant is available ?
There are a couple of days when the new zodiac is released where the previous one is also available, so at that point you can plant two.
Otherwise you'd just leave the plants for one in the garden and plant up new ones as they are released, until you have the number you need. Or you complete each attracting part as each zodiac is released, and so complete the quest over a number of months.
