Crewyd y Meees gan Cynhyrchiadau Ceidiog ar gyfer S4C ac ers eu darllediad cyntaf yn 2005, maent wedi cipio dychymyg gwylwyr ifanc y sianel. The Meees (the Baaas in English) were created by Ceidiog Creations for S4C and since their first broadcast in 2005 they have captured the hearts and imaginations of S4C's young viewers. The series features the lives of a family of multi-racial sheep who live in a cosy cottage in Wales. The family is lead by Costas, an opera-singing Greek sheep who recycles other peoples rubbish into weird and wonderful creations.
