I must tell you that Froggy belonged to the marionettes' hard sentry-go, those who make threads to manipulate their fellows. Their main activity is the reading and then the elaboration of complex speeches. With the words of their speeches, they make threads. Within the hard sentry-go, you' re not there to enjoy yourself. Besides, to prove they are serious, their mouths are drawn downwards and their bodies are completly stiff. That was a fact unknown to Brain Bird.
