When a group of two or more excited dogs race down a path/stairway/hallway/whatever.
When the dogs get really excited, and want in, it is always dramatic when we open the door, as that always triggers a dogalanche.

Bionicle is prehaps one of the first story-based toys made by Lego (For kids with little or no imagination)
Based on Lego's TECHNIC line, it has, IMO Defiled Technic's name of bricks, gears and shafts altogether.
Bionicle uses parts made for the set only, making other sets that one part unorigional. To make things worse, Sets (In numbers of six) have basically the same parts, except for cosmetic parts, such as tools and shields. This make the sets a new expireince only if you buy one.
And DON'T get me started on Bionicle-Based My Own Creations (MOC's) They have the worst storyline-based and construction of ANY lego-creation.
(Though I would have to give them credit. Working with those one-set-use-only parts is impossible)
Bionicle, If it were not for the storyline, would suck. Their grandparents, the Throwbots, are better.
