@sozobe,
Kangaroos get "born" when they are basically still foetuses, and thay have to climb up to the pouch, where they attach to a teat, and get born again months later.
Both those "babies" got born a ways back...even the first one is quite mature.
It's unbelievable watching that weeny, red, pathetically tiny li'l foetus climb all that way to the pouch...
