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.
