The Savanna is a grassland with very few trees and it's the first level in Giraffe Evolution, where crates are delivered. Crates must be emptied and Giraffes fused or the level will become full. The maximum number of Giraffes in this level is 10 to start, but later on can be upgraded to 16.
The following giraffes can be found on this level:
A warning screen appears if you try to purchase additional giraffes when the area is full. Also, there is a small red timing bar in the lower lefthand corner of the screen that indicates the time left until the next crate drop or shows a FULL! message in red whenever the Savanna level has hit maximum capacity.
