It's just a runt. Best way to tell a peanut is by looking at the ears, not size. Peanut have tiny, triangular ears. This kit has normal ears. In the US, mini lops don't have the dwarf gene. They do in the UK and australia however
The easiest way to tell the difference is the ears and forehead. If the ears are small, pointed, and set far back, and the forehead is large and the eyes bulging. The picture you posted shows the forehead but the ears look normal and not pointed, hopefully not a fader!
