I cannot help but get that kinda "Ah, so cute!" reaction from whenever I imagine Shiny playing with bubbles and this story is just supercute and bubbly, Sasuke! Totodily love it! (-^.=.^-)❤️️

As like in other cases, your writing yet again shows that you put care and sentiment into discovering and presenting your characters well. Shiny's personality of a bouncy and playful lil guy who shines with much curiosity and optimism, comes through sweetly here and the premise that you thought of here made for a supernice surprise either.
On one point I actually had imagined Shiny playing for example with a machine that would spit out balloons every now and then but bubblebath suds are also just suds of fun! =D

Shiny is such a lil funny fellow here. He is so eager for his bath, runs around the house, bounces between foam and suds when things are getting silly and somewhat adventurous and is just embracing the situation wonderfully.
I can pretty much see Shiny ordering those suds in pill form again. Maybe next time he might end up floating out of his bathtub as he's getting suddenly encapsuled in a big bubble, or perhaps he cannot help himself and look how the pills taste, ending with his waterfilled Totodiletummy to spout out copious amounts of bubbles? It's great when a nice story gives you already ideas for a round two. ^_^

Hope that you also had an enjoyable time with this one, Sasuke. I surely find it to be like one of my personal favorite reads as in the innocent nature of Shiny it just feels lovely overall. I bet that even the whole cleaning the house part is not much of an issue thanks to the fun solutions that people got at their disposal in his magical and scientifically practical world.
In any way, I will tresaure it lots and wish you and everybody much fun and relaxation for their next bath time. =3
