Reason(s): {{{1}}}

In this episode, Y wants to become a vowel.


The vowels, A, E, I, O, and U, sing in harmony, until Y shows up. E says this group is vowels only. Shy Y sings about his desire to be a vowel. T and R appear to tell Y that all he has to do is tr... But they need a vowel. The five vowels show up.

t-r-a, TRA!

t-r-e, TRE!

t-r-o, TRO!

It doesn't work. I and U refuse to help them, but Y can do it.

t-r-y, TRY!

Y becomes striped like the vowels, much to their surprise. The episode ends when Y sings harmonically with the vowels.

Nonsense Words


At first, we didn’t know what they mean. However, according to Mr. Yokai:

"Definition of tra-la. —used to suggest gaiety, lightheartedness, or playful derision especially in song."

"Definition of tre corde. : with soft pedal released —used as a direction in piano music at the close of a passage una corda."


The name of Arifmetix's Numberblock 2.5Pi.

Also the word for "believe" in Swedish, Norwegian, and Danish.
