One Hundred is the thirteenth episode in Season 6.
One Hundred shows us what she's made of in a big song about being big.
One Hundred is confirmed to be female in the description of the episode on the CBeebies schedule (that was before the episode aired on TV).
Song: I’m Big (So Big)
101 Ones are seen on screen at the same time in one scene, beating
The Big One by 100 Ones. When 100 mentions a way to count to 100 quickly (by tens) there are much quicker ways to count to 100 such as counting by 20s or counting by 25s, up to the number 100.
This is the first time 100 uses her rectangle rays. The second time in 100 Ways to Leave the Planet
This is the second time a
compound numberblock from blue level 5 (99) appears, the 1st is The Big One. This is the first and only episode where One Hundred is seen vertically.
