Japanese(?) to English anyone?

I have been playing a game called LocoRoco and would like to understand the lyrics of the theme song and the stage music. I'm not sure is it japanese, but I think so. I found the lyrics from internet.

Theme
Bajumbo moi noi noi jecker
Dabatto bunkergait jun jun
Nora juerue-rotto pura-pura petto
Puraret dum dum
Papuranoi noi noi jecker
Dabatto bumperget tum tum
Ora poerketino bookeran tan-tan-so

Bokeretyo kyenturanai mimani unlalhood-cha-la
Terra hooki-ra pishi-to diki-ra poody-to
Seni-kidi koseibo
Kokorenkyo kyenturanai mimani unlalhood-cha-la
Terra hooki-ra shishi-sho tusura hajiki yo

Bajumbo moi noi noi jecker
Dabatto bumperget tum tum
Nora juerue-rotto rokorolo-petto
Pura-purarun dum dum
Papuramoi noi noi jecker
Dapatto bumperget tum tum
Ora poerketino bookeran tan-tan-so

The stage music

this isn't Japanese. I'm not sure what language it is, though.

Ok, I was just wondering is it real japanese or just gibberish.
