Obki (S), Keep Earth Tidy (S)

Obki learns about energy wastage and realises he has left more than a few things switched on...

The Orb helps Obki to trace the microfibres from his trousers all the way to the miniature deep blue, where the local creatures aren't fussy about their food.

Obki's doodling session gets interrupted when the Orb notices he's been wasting paper.

Obki discovers how important seagrass is for our environment and is inspired to produce a new hit song to raise awareness for it.

Orb show OBKI just how much pollution is created to deliver fruit to our supermarkets. Time for a local solution!

When the orb realises that the underwater base is running on coal power, Obki provides them with a new sustainable energy source.

When the Orb's eco-sensors detect that a local town is overrun with air pollution caused by car fumes, Obki transforms the cars into bicycles.

When a beach littered with rubbish turns out to be too big a job for just one alien, the orb's malfunctioning cloning ray comes in handy.

When the Orb explains that wildlife habitats are being threatened by aggressive palm oil farming, Obki declares a strike on using all palm oil products in the base.

The Orb explains that insects struggle to live in cities because there aren't enough green patches for them to live in, so Obki decides to create some new ones.

With many humans still unsure how to help the environment, Obkiuses all he has learned to show them how they can make a difference.
