A month has passed since the Poison Joke incident and now, the trio has adjusted to living as babies. And it sure looks like Fluttershy has gotten the hang of the role as she is now teething on the ear of a bunny plush. They have been in great hooves with their current caregiver and they don't mind it one bit.
And yeah, by the way, that weird toy is not a peanut, it's a type of rattle.
The front is Fluttershy, to the left is the Seapony (I don't know her name), and the right in the back row is Peach Watermelon, or Peach. And yes, Peach has a different eye color, that is actually because she has heterochromia so that means she has two eye colors, one of her eyes is blue and the other is purple.
