Here is a storyline idea for season 3 of Puppy in my Pocket. If you want, you can insert your ideas in the comment section below. Let's start.
During dark night,Santi X and the rest of the bad guys go and steal the giant Friendship Heart and the other smaller ones. They use them the wrong way and cause a crossover and the real world and Pocketville merge and become one big world. Cities and houses spawned every blank area and the Pocketville earth became bigger because of this. After this disaster, the 5 hearts spread threw out the world and the heros must collect them before the two worlds fully start merging.
the first main cast and most of the fanon charecters here.
