Codee - Parrot, Frog and Sheep extensions - how to access?

Hey everyone, I recently bought a Codee (aka VirtualPet) and a Bit.

Funny enough the Codee comes with the firmware loaded Penguin, but also with 3 extensions (Frog, Sheep, Parrot) but the actual Codee HARDWARE does not have a slot to plug these extensions into — or am I missing something?

The BIT does have the “wacky robots” extension slot, but when I plugin the Parrot/Frog/Sheep extensions it recognises it (e.g. “Frog Pet inserted”), but apart from showing the parrot/sheep/frog as an option on my Level1 avatar I don’t see the option to access the VirtualPet software on my Bit.

My question is: how can I access the Parrot/Frog/Sheep pets on my Codee which comes preloaded with the Penguin pet?
