Poochie driving.
Poochie was Xaq's first canine sidekick (and pet). He accompanied Xaq on a few missions. One adventure was started when Poochie escaped, causing Xaq to come after him. He was later succeeded by Puppy and Scooby. (Series 1)
Many years later, Poochie became a taxi driver when Xaq appeared in the back seat of the car. Xaq didn't realize it was Poochie at first. Poochie drove erratically, crashing into things and doing the opposite of what Xaq instructed. It was only when the car was backwards that he was able to drive normally. He smashed into The Rich Kid's castle, with Xaq being thrown inside. ("PCG Anniversary Special Part II")
Alternate Timeline[]
An adult Xaq was sent back in time to his childhood, where he met Poochie again. Poochie detected something off about Xaq, and kept sniffing and acting confused. (Xaq Series: Untitled)
