The Imagination Box: A Mind of its Own

There was a sabre-toothed tiger in the playground. Wandering thoughts, Tim had come to realise, were extremely dangerous things.
Nearly a year has passed since Tim, Dee and Phil the finger monkey (with the help of some fire-breathing bear-sharks) defeated Wilde Tech Inc and destroyed the imagination space. But since then, it's become increasingly clear that there's something wrong with Tim. His imagination seems limitless - anything he imagines immediately appears in front of him, with no need for the imagination box. Which has both good and bad consequences.
Then, in the blink of an eye, everything changes. Tim wakes up and discovers he's in his old orphanage. No one, not even Dee, knows who he is. He's completely alone - his worst nightmare. But soon he realises who is to blame. His old enemy, Clarice Crowfield, has hijacked a new, all-powerful machine and created a reality where she is in charge! Tim must find Professor Eisenstone, convince Dee that they really are best friends (and, of course, recreate Phil) - then literally put their world to rights.
