Misperceived Monotreme

Perry misses his 100th battle against Dr. Doofenshmirtz when Candace takes him to the Charity Pet Wash with her. Perry's absence goes unnoticed when the zookeeper's typical platypus at the Danville Zoo stops Dr. Doofenshmirtz's plan to zap his brother with his "Least Likely-inator." Meanwhile, the boys build a fun house Phineas and Ferb style.

Songs

Perry's entrance to his lair
''Carl tests all the secret agent doors to see if any of them are jammed (Perry was late for his mission). The zoo platypus smells Carl's sandwich and instinctively walks into the tree elevator as it opens.''

Errors

 * Why would Monogram and Carl upload Agent P's battle on the internet it would expose his identity
