Glimmerbat time limited?

[dizzy7373]

I have just finished the Adventure to get the spooky glimmer rocks, unfortunately I only got 1, so does this mean the adventure drops 1 rock per trip, so another 4 days of adventuring to get all the rocks.
I only have 6 days to complete the goals and reading through the upcoming quests, there is one more adventure after this to get the glimmer bat.
Do I need to spend gems to speed up these tasks as the time left is very close to how much time is allowed to complete it.
Also are the rocks and glimmer bat a definite drop on each adventure, or are they rare drops so it will take more than the 4 adventures to get 4 rocks?


Edit(KP)

The Glimmerbat is a limited item. Once the quest expires, it will no longer be dropped from the Adventures.
