Since everyone refers to giving tree cubs as 'potatos' when they don't like them [which is very often], I think for April Fools 2018 that linearts of cubs [0m-11m] should be turned into actual potatos or a false ''Mutation: Potato'' for the day. :P The former would probably be best.
As a follow on, depending on the cubs genetic group perhaps there would be a different varation of potato - eg. red:rooster,cream: sweet potato,gold:baby potato.
