The new additions to my minfig collection came from three polybags, the 30310 Arctic Scout, the 30111 The Lab, and the 30302 Spider-Man Glider.
The 30310 Arctic Scout is part of the Lego City theme with an Arctic subtheme. The polybag contains the Arctic Scout minifigure and a small mini-plane. This is my first minifig from the City theme. The minifig is quite nice with the helmet that has a removable visor. The mini-plane is not that great since the build feels a little fragile, but it does have some nice components.

The 30111 The Lab is a polybag set from the Harry Potter theme. The polybag contains a Harry Potter minifigure and a cabinet of potion bottles. This is my first Harry Potter minifig. The minifigure is a nice additon to my collection since it is a very popular character. As for the other contents of the polybag, I'm not as excited. The potion bottles could probably be useful when I start making MOCs.

The 30302 Spider-Man Glider is part of the Lego Marvel Super Heroes theme. The polybag includes a Spider-Man minifigure and a glider. With Batman as my favorite DC superhero, Spider-man is my favorite superhero from Marvel. So, I'm quite excited to have this minifig. As for the glider, it is a different story. I think Lego could have created a better-looking glider.

I hope Lego releases more polybags in the future. I will definitely be on the look-out for those polybags.
