Once upon a time, there was a castle on a square island. The entire island was surrounded by a 14m wide trench.

The Romans still managed to cross the trench. How did they do it?

Fate has decided that you will only be pleased to meet me when you need me

Maybe that is why, when I am working, I start working

The green one says, 'We have 27 legs altogether.'

The yellow one says, 'We have 26 legs altogether.'

The red one says, 'We have 25 legs altogether.'
