hopper problem(12v revvy)

i have a 12 volt revvy (the red/gold one from action village) and i was playing with it today and during the last session it just decided to cut out on me. at first i thought it was because of some clogged breaks i had in there, but i cleaned it and all, and when i switch it on it doesn't spin the agitator. it looks fine, nothing obvious is broken or anything, and it's only a few weeks old. fresh batteries, i put them in every which way and it didn't work. anyone know what's wrong?
-edit- i just cleaned the eyes too and it's still not working so that can't be the problem
-edit2- ah nvm it was the eyes, i just had the batteries in wrong after i took it apart

-edit-^from yesterday; today i played again and it just died. like that *snap* it worked before i got out there and the batteries are only a few days old, hopper only a few weeks old, batteries ARE in right this time, i checked time and time again.
