Pajama Sam/WMG
The events of Pajama Sam 2 caused the climax of Ouendan 2
When Pajama Sam had accidentally pressed the big red button, it had caused parts of the World Wide Weather to scramble. One of the machines affected was the sun machine, which didn't get its fuel due to the lack of Wing Nut. In result the sun was on the verge of dying. As Pajama Sam was getting Wing Nut back to its place, the both rival Ouendan realized the need to teamwork. The teams cheered and so did the Earth, giving the Sun enough energy to survive longer. Eventually Wing Nut is restored to his place, and the sun was restored to full health.

Pajama Sam owns at least two editions of Pajama Man issue #1, each with a different cover
Each cover corresponds to one of the stories in the issue. The edition with Dr. Grime on the cover is by far the rarer of the two.
- It could also be an in-universe Continuity Reboot.
