Pufferfish is a puffer discovered by Richard Schank in 2014. Being found in a symmetric soup, the puffer is almost natural.[1] It consists of a pair of b-heptominos whose debris is stabilised by a backend.
It is the first known c/2 object that doesn't have any parts of periods 2 or 4.
On December 27, 2014 Ivan Fomichev found a non-trivial (dependent) c/2 fuse of period 36 for pufferfish's exhaust, that enabled him to assemble the first wholly high-period c/2 spaceship and rake.[2] A few days later 'glider_rider' found some smaller rakes.[3]

Synthesis
The second pufferfish-producing soup Richard Schank found resulted in a 15-glider synthesis proposed by Chris Cain.[4] On January 8, 2015 Ivan Fomichev made a p160 pufferfish breeder.[5]
