Y is the 25th and youngest Alphablock in the letter gang.
Y is voiced by Lizzie Waterworth.
He is a yellow block with a lowercase letter 'y' in his 'head'. He appears to have a tiny curl of hair sticking out from the top, and freckles on his cheeks. He is a semivowel (a vowel that is a consonant).
Y's lowercase shape makes the "u" sound in Cyrillic languages.
