A brilliantly bonkers story about an octopus who lives on the roof, by two award-winning and best-selling picture book creators. When a giant octopus arrives, the children LOVE their new friend; he makes the perfect slide and is fantastic at football! But some of the grown-ups aren't so pleased. Will they drive him away... or will they realise just how helpful an octopus can be?

Un dydd daeth octopws aton ni i eistedd yn braf ar ben to y tŷ. Nid pawb sy'n hoff o'r octopws i ddechrau. Ond pan ddaw pobl i weld ei werth, mae'n gwneud ffrindiau gyda PHAWB! Felly pam mae'n DIFLANNU un noson? Ydy e wedi mynd am byth? Oes SIOC ar y ffordd i bawb?
