An investigation of which animal has the smelliest poop has been requested, so Robert (with Akiyama dressed up as a wild man) and Kimori set off for Tobu Zoo to smell for themselves. After discovering that the Red Panda's poop smells like grass or tea, the group eventually ends up with the following list:
5) Giraffe
4) Rhino
3) Elephant
2) Zebra
1) White Tiger
