Why so sad?

This is Luke Chueh Mecha Sad Bear. Mr. Chueh as made a career out of putting sad faces on cute stuff, and also often splattering them with blood. Thumbs up for that.

What's Mecha Bear up to here? Is he looking for a hand shake, a hug. Most likely he's looking to take a giant bite out of your neck.

 Wait! Don't leave me alone!

Damn, there goes another meal... um I mean friend.

Cutest mecha tail ever. 

All systems are GO!

Who let that guy in here? It took me a whole day to clean up the last time these two got together.
