Another funny glitch

[Rob-48]

If you've been following the "Expand a level" thread you might have seen this one... it worked out quite well as it seemed to be the only way to beat a really fiendish level.

I somehow managed to get a projectile to "cling on" to a yellow block and ride it down as it fell, with a rod going right through the block. Then it freed itself after a few seconds and went on its way to the goal!

It kind of reminds me of a koala bear or something with the baby on its back
