Now this brings back memories! My younger twin is now 17 but when he was younger up until he was 13 he collected DragonballZ figurines and memorabilia! He should still have a lot of it - the wall clock, etc.
I should add that the reason he colelcted those is that his father collects Superman memorabilia and he was following in dad's footsteps :) His twin used to collect Spiderman stuff. Theyve both outgrown those now but myhubby still collects Superman.
