Yeah, we call it simply "exploding" xD
He does it mainly in the street (I also daydream while walking and there is no conversation), wherever we go he is jumping and making noises to fit his thoughts.
- What are you thinking about, son?
- Nothing, nothing.
- Surely it was something, you were
exploding.
- Oh.
Li li, I do think he would fit. If only he were a bit older and could speak some English! :D
Actually I'm quite surprised he never showed any interest in my knuffel, whenever I'm leveling them up or whatever. Considering how he loves (learning facts about) Pokemon I kinda expected him to get curious about my pets!
