The Slimy Cave Full of Slime

Huw Aaron is a Welsh cartoonist, author and illustrator, and the creator of the bestselling Sleep Tight, Disgusting Blob and Unfairies, both of which were shortlisted for the Waterstones Children's Book Prize 2026 - a historic achievement. After a short and fairly hopeless career in finance, Huw found a niche as a magazine cartoonist, producing joke cartoons for, among others, Private Eye, Prospect and The Spectator. Huw then started making comics and illustrating children’s books in his native Welsh. Since 2013, he has written or illustrated over 60 Welsh-language books, and has won numerous awards including the 2023 Tir na n-Og and Welsh Children's Book of the Year prizes. He was also founding editor of the comic Mellten, and presented the weekly art programme Cer i Greu on S4C. His newest stories are Monkeypig and Unfairies: Death by Toad. Huw’s harshest critics – and his best friends – are his wife Luned and their two daughters.
