There is also an Alphablocks episode with the same name , along with a Colourblocks episode with the same name .
Big Bob is the only one who spoke in the series. It is unknown if the rainbows will return and Kevin and Rainbowlina will speak.
However, Kevin was mentioned the first.
Due to her name, it’s likely that Rainbowlina is the only female rainbow. It’s also possible that they’re all non-binary.
In real life, rainbows are mirages and would be intangible if you could get near them.
