Summary[]
The Creature Book gives a summary of all your creatures and allows you to merge them in a controlled setting. It is accessed by tapping on the Creature Book Icon at the right hand side of the screen. It sometimes shows a number indicating how many 3-merges or 5-merges you can currently make.
Information[]
The Creature Book shows your current Magic Power and the number of discovered Creatures. Each creature has 8 separate levels (not including eggs and nests).
Merging[]
You can either merge them as 3 or 5. Tap on the Merge 3! or Merge 5! buttons of the creatures you want to merge and then click OK for them to merge. Note that if you have 5 creatures or above, you cannot merge 3 without doing a manual merge within your garden (i.e dragging one on top of the other two).
Remember: Merging 5 is always better than merging 3.
If you merge 3 or 5 level 4 creatures, 1 or 2 nests are created. Your magic power will go down so find the nests and tap them for new eggs to merge again.
Renaming Creatures[]
You can rename your creatures by tapping on the icon at the top right hand corner. Duplicate names are allowed, however names are limited to 24 characters. Profane or vulgar names are not allowed.
