I always allow my kids to choose their birthday cake theme (nothing too definite, I'm not brilliant!), and have suddenly come up against a request for a "Super Mario or Pokemon" cake. Sadly, I've never played Super Mario, or seen Pokemon (terrible, I know - now if it was LOTR, or Marvel comics, or Miyazaki, I'm your geek, but...) so I'm a bit out on a limb here - any ideas? Nothing too complicated please!
[edit: Just for ref, here are some of the cakes I've done in the past. I'm no expert, but I'm not a complete klutz, either!http://www.facebook.com/album.php?aid=119247&id=587040131
LOTR request became the One Ring (yes, the runes are accurate!)
Harry Potter request became Fawkes the Phoenix
Doctor Who request became a TARDIS]
and so on
