I would personally think that alot of merchants would not have the willpower to cheat a baby. It's probably how people would identify low tier bad guy.
@icarushector The manga with how familiar the rabbit is called "VRMMO de Summoner Hajimemashita", while for the manga with a familiar a goblin I put your name under spoilers because it happens later.
The manga is called
Isekai de Mofumofu Nadenade Suru Tame ni Ganbattemasu
.
Actually, if you want, there is also the manga Dungeon Nursery where there is a goblin familiar, you can find it concluded on mangadex if you want something already complete.
@icarushector I just sent you the friend request, if you want to accept it.
In this way if other manga come to mind where we are familiar with rabbits and goblins I can tell you more easily.
Because I remember a third of manga with a familiar goblin, only that it will be that I read a lot of manga but I don't remember the title. '^^
