Sonichu (species)
Sonichu is the name used for Chris's imaginary species of electric hedgehog pokemon. Although the term sonichu can be used as a general name for all creatures in this species, it is usually only used for the male gendered specimen. When referring to female sonichu, the term rosechu is used.
Sonichus and reproduction
A sonichu's penis and testicles reside entirely within its abdominal cavity. While the testicles are permanently contained behind a "bone-like structure" for protection, the penis can emerge for urination or intercourse when the sonichu leans forward, causing the erect penis to "slide out" purely by gravitational force. This presumably means sonichu must be erect in order to urinate.
The sonichu's sperm cells rest within a pouch inside his body. During an orgasm, sonichu will release between 100 and 500 milligrams. Sonichus are prone to premature ejaculation, and can carry STD's.
