Bio-Pellets

Bio-Pellets are an official source of bioenergy for Creatures 3. They show up in the creator machine as "Bio-Pellets for the recycler", and five are injected at a time, next to the C3 creator. Each Bio-Pellet gives 100 bioenergy when recycled.

They can be downloaded at the CDN. Make sure to right click the link and choose 'save link as'.
