It's Yoshinas! And her evolutions Anaishow and Anayoshis

type: pshychic and grass(can use bulletseed and razorleaf, cannot use vinewhip)
uses tail for hypnosis
first stage uses mostly pshychic attacks and disarms opponents with it's cute looks. But it doesn't mean that it won't bite you by the rear.
second stage uses sharp claws and can use it's tail to phisically strike.
third evolution has a really long tail that can be wrapt around a grown man. it also uses manly psychic attack, for it is big and not very fast.
Yoshinas is a little over Pikachu in size and Anayoshis is about Arcanine size(can be mounted) Third stage doesn't have any "clawing" attacks despite having claws. His claws are too short

So, that's some info) And, yes, it's pineapples on them tails XD actually name Yoshinas is a combination of my fursona's name and russian word "ананас", that means "pineapple" XD
