I’ve noticed my greninja bubbling it’s young recently. Like the 3 froakie babies will be in a nest of bubbles. Is this normal?

Absolutely. Greninja frequently bubble their young to make them comfortable, to protect them from harm, or to keep them warm. Assuming you live in the northern hemisphere, it’s currently autumn, going into winter, which means the temperature is dropping. Your greninja is likely preparing for this. In addition, the unusually warm temperatures we experienced through the summer may explain why you’re only noticing this recently—because it wasn’t as needed a few months ago.

Alternatively, some greninja subspecies bubble their young to teach them how to create bubbles themselves. By surrounding them with bubbles, the greninja forces her young to watch her as she creates the nest, so they can figure out how to weave their own later on in life.

In short, so long as your froakie can breathe and stay moist, they shouldn’t be in any danger.

The Froakie Line

Froakie
The Bubble Frog Pokémon
Type: Water
Official Registration #: 656
Entry: One of three pokémon traditionally offered to new trainers at the beginning of their journeys in Kalos. True to their species name, froakie are known for their tendency to protect their delicate skin with bubbles. However, skin protection is just one of the many uses for these bubbles. Another use is, of course, to protect a froakie’s eggs when mating, and the foam itself is typically generated early in the fertilization process when the male mounts the female to agitate her foam sacs. Thus, trainers, when you find your male froakie hugging your female froakie from behind to create a cloud of bubbles, rest assured that there will soon be a daycare owner who will tell you that an egg has suddenly appeared and that he has no idea how it might have gotten there.

Frogadier
The Bubble Frog Pokémon
Type: Water
Official Registration #: 657
Entry: The evolved form of froakie, by battle experience. Supposedly, frogadier possess unparalleled speed and dexterity that enable it to achieve incredible feats of agility. For example, according to one report, a frogadier owned by a Kalosean researcher has been found to be capable of scaling a 2000-foot tower within a minute. Of course, considering the fact that Kalos’s tallest structure, the Prism Tower, is only 1062 feet in height, how this specific ability has been tested is a very good question.

Greninja
The Ninja Pokémon
Type: Water/Dark
Official Registration #: 658
Entry: The evolved form of frogadier, by battle experience. Gifted with ninja-like skills, greninja can appear from seemingly nowhere and generate a barrage of throwing stars made of compressed water. Incidentally, yes, these stars can, in fact, shear through metal; yes, the author has learned this the hard way; and yes, he has not yet forgotten that a certain Kalosean professor owes him quite a sum of money for the destruction of one rental motorbike thanks to his protege’s greninja.
