Casi Tessellating B

Vincent Pantaloni shared these neat almost tessellating tiles from @AY_puzz on twitter: I made type A (GGB here). I had to think about B. These aren't exactly B, as the author added a peak to minimize the gaps. I like the smoothness of the tile better this way. What do you think? Also, since we have quasitessellations, I like the Spanish joke of Casi (almost) Tessellating.
