Mr Harrison the snail
Suppose the worm
Ariadne the spider
Anorak the pillbug-come-woodlouse
Ladybird the ladybird
Lambeth the beetle
Ancient the caterpillar

These are all the characters in the show. So yes, although they are 'Creepy Crawlies', they've been turned into funny looking/acting characters, as this show was created with a child orientated audience in mind. Some of them have human characteristics / look like humans but have their original look. For example, a beetle with two legs + arms with no shell.

This inspired me to create a character along the lines of this, so a hyperactive boy who looks like an insect? Clothing? Or an insect that looks like a boy o_o
