Poké mon's fire-breathing dragon, Squirtle, butterfly and hot monkey ... all come back at last?

I don't think it will come back according to the development of animation. Squirtle seems to have gone to the fire department and won't come back ... but in one episode, he came back to help Xiao Zhi and finally returned to the fire department. The fire-breathing dragon went to the Dragon Valley, where the fire-breathing dragon gathered. The fire-breathing dragon stayed there to exercise himself. The big butterfly flew away and never saw it again ... The hot monkey gave it to the boxer and never came back.
