Small white ghost-like creatures from the Moomin series. I remember that they grow from seeds, travel in odd number (trying to reach the horizon) and go crazy over thunderstorm – then they gather in groups and charge with electricity.

I remember plenty of them on hill, swaying in silence full of tension. Those two get lost and wandered far from Moomin land. Help them multiply and find new homes!

I’m sorry guys, but pattern is no longer avaliable.
