This is a transcript for the April/May 2020 'Ebrenn y'n Nos'  piece I prepared for Radyo An Gernewegva, broadcast in #481.

Cornwall to become dinosaur experience park

Apr 1, 2020

According to an anonymous government source, Cornwall is going to gradually transition to be a dinosaur experience park.

A series of comments by a Conservative MP who has forgotten his microphone was still on during a late-night videoconference port drinking party said something equivalent to "now Cornwall, [noise obscures speech] , we go to their second homes there but we don't understand their societies, they aren't like us we might as well be in [redacted]. We should help the seagulls evolve back into dinosaurs over time"

Some of my plants that live at my parents house 28th March 2020

Mar 28, 2020

Here I show you around the garden at my parents house, including some of my own plants that currently live there, including the dahlias and lavenders grown from seed which aren't looking very happy after being exposed to some unusually dry air, a camellia seed that was originally harvested from one of my parents camellia plants which has germinated, chilli seedlings (Chocolate Cherry and Aji Lemon/Yellow Cayenne) - harvested seeds from plants I grew last year, more than one Kea Plum tree, Kiwi fruit, tulips, gooseberry, Chilean Guava (Ugni molinae), an apple tree, a pear tree, Dicksonia antarctica tree fern, and various Camellia.
