FROM LEVEL 11
Blue Burr.
A leap into trouble.
An electric Burr hops towards the nearest swarm, lands on its prey and shocks nearby touching creatures. Two can hunt together from Level 21.
Watch the landing
The Blue Burr moves in noticeable hops, with a pause between them. It can land on another Burr, then springboard straight onto a targeted creature within twice its normal hop range. A completed herding line blocks either leg.
Break the chain
Its electric shock kills the touched creature and spreads through bodies touching or within 2 pixels, including neighbouring swarm groups. It disappears with the shock. Each ordinary creature lost removes 30 points, or 80 for a crown, even below zero. Lines and shields break the chain.
More than one way to hop
One Blue Burr hunts from Level 11. From Level 21, up to two can be on the pond at once. They arrive and return after random delays.
