If you know him, nothing more there is to say…
If you don’t then here it is (copied from Wikipedia…): Perry the Platypus, also known as Agent P or simply Perry is an anthropomorphic platypus from the animated television series Phineas and Ferb….

My Perry is about 11cm when sitting and 16cm from feet to head.
He cannot stand on his own feet. Pipe cleaners can be used inside his limbs for the option of bending but it won’t carry Perry’s weight. If you intend to give the toy to a child you better not use the pipe cleaners.
The pattern is fully detailed in 13 pages with many pictures that explain each step of the work and the right way to assemble each part until you get the final smashing P.
The Original pattern was crochet with cotton yarn but any other yarn will do. Gauge is not important for Perry’s well being..
Please read the whole pattern before you start crocheting.
