Zoo or False? / Master Pho

S1 E11: Zoo or False?: Riley is upset at how the animals are mistreated at the zoo (including her favorite black panther Sasha), so she replaces the zookeeper with a true animal lover who will improve their surroundings. But much to her surprise, the new zookeeper wants all the animals to be in their natural surroundings - literally. She lets all the animals free and now they're roaming around Pleasant Hills causing chaos. Master Pho: When he's not getting any real martial arts training out of his karate class, Todd begs K to teach him some of her moves and get her old instructor (a Kill Bill-type martial artist) to teach him. After K says no Todd takes matters into his own hands and replaces his instructor with the legendary Master Pho.
