"Walking Down The Parallel Space Tunnel" 

These existences were what the two fairies called 'parallel space and time creatures'. 

These creatures didn't have any fixed image.

The first creature that Ainsley saw looked like a long and fat white worm, wriggling and drilling into the tunnel where they were in. 

Fortunately, the worm was not that big, only the size of a tiger, and it was not aggressive. 

A tiger was already big in the eyes of a child, but Ainsley expected to see huge creatures as big as whales, elephants, or as tall as skyscraper buildings...

That's why, Ainsley was thankful that they didn't meet a monster as big as a skyscraper or something like that. 

Of course, if the baby saw the space outside of the protected tunnel, she would not confidently sigh in relief, unlike now. 

After all, there were indeed too many huge creatures out there, so big that just one of their eyes was about to cover the whole tunnel that could fit several hundred people.
