This Seeking Tech guide will show you an Easter Egg involving the multiple dogs and one cat you rescued in Astro Bot. Unlike the other VIP bots, these characters will follow you around once you give them a little tap.
You will be able to do this with the Pomeranian from Tokyo Jungle.
The two Aibo dogs can also follow you after rescuing them and then getting the Doggy Toys prize from the Gatcha Lab.
Moreover, the Shiba Inu from Humanity can follow in your footsteps as well.
You can also get the cat from Stray to follow you when you rescue it, and then get the Curious Kitty prize from the Gatcha Lab.
