Albert the Alien Chapter 4 Page 17

Hee hee, Wally’s a dog.

The latest Albert the Alien is full of action!

The kids discover the alien door is like Albert’s locker (trans-dimensional distortion device, or TD3) and must lead to another location and not through a physical barrier (like the wall). Earth doors let us pass through physical barriers, but alien doors may allow people to traverse long distances – or into rooms otherwise not reachable! We will find out more about the mysterious alien door as the series progresses.

Wally also finds an alien device of some kind that turns him into a puppy. You can’t go wrong with comedy gold like that.
