Dialogue of Botley For Pointing
- "I suppose we should give you the two-sent tour of the place. Over there's the kitchen. Back there's the art gallery. Inside you'll find the Professor's virtual collection of art and a painting gallery to create your own work. Through that door is the music hall. Behind that door are stairs leading to the Professor's jumbo electro generator when we need to power up. Finally that stairway leads to the upper floors."
