Evil Twin PS2 Q&A

Q:

In area 4 of the flyers. i have just wa;lked the bouncing bridge. then i come to a windmill, and when im inside and on the attick, i am supposed to blow up all the crates. i can blow them all up but two, the last iron one (the middle one of the three next to eachother) and not the one with thew drawing on it. i know there should be a bird here i have to catch with bubblegum, but there is no bird. that connectyed to the boxes that dont blow up...well, im at a loss here...?
