Anyone who's wandered through this rambling depository has possibly come up against the continuing enigma that is HeartCatch PreCure!, the seventh (and easily best) in the girls' anime concept series developed by Toei Animation to lasso young girls' hearts, their mums' wallets, and the imagination of otherwise cynical types who once dug Sailor Moon.
For the first 24 episodes after the show kicked off in February, the closing titles theme song was 'HeartCatch☆Paradise!' by PreCure regular Mayu Kudo - and as the YouTube gems below vividly display, it's been quite the hit here in Japan for the rather eccentric dance moves as much as for the groove (the first one is the real McCoy).
I think my favourite is the Blues Brothers inspired number.
