For each world, Jean-Yvon had to:

• Create the landscape (with 2 layers for parallax effect). He (re)discovered hand drawing/painting with a Wacom Bamboo tablet and he is talented! Each landscape is composed of three environments (like desert/savanna/jungle) for a total size of  9000*640 px (HD).
  
• Vectorize 24 animals (Illustrator) and animate them in Flash (skeleton technique).
  
  
  Each animal contains distinct animations (like moving ears or head, eating, ...) for a total of 30 to 50 frames that were converted to sprite sheets with TexturePacker in pvr.ccz 16 bits format.
  
• Create 24 Bobble Head cards
  
• And all associated items...
  

He also had to design all interface elements and the mascot.
