Here's what is to come: a comic cutscene.

In the episode, I'll make each comic panel appear every 2 seconds, like in Angry Birds Rio. The comic is easy to understand as you can tell what's going on. You can press the Jump button at anytime to skip the cutscene into the starting level. It's possible with layers and events, though.
I'm also planning on comic panels that are odd shaped (into triangles, trapezoids) like in Rovio's games. Once you ride the rocketship to Planet Spore, the cutscenes will tell you that Bowser is trying to activate the Bowser Laser, and locked away his space station with the Comet Pieces. The comic strips may be odd-shaped in that.
Note: Since Toad already ate the mushroom before the level can start (he possibly ate the mushroom while talking to Rico, which is not in the COMIC itself), you can still get a mushroom in the Chest.
