There is a new grandpa timed goal
Prize: Animated Owl
When you finish goals, Gramps still drops by and gives you 9 marshmallows each time!
edit(KP)
Minimum level for this goal is 12.
Grandpa drops by every 4 hours.
Grandpa can drop 2 or 3 Marshmallows, but it will depend on your level.
There's also a VERY small chance that he will drop a large amount of marshmallows for players of all levels.
