I find Prowl's transformation to be fairly intuitive - much more so than say MP Rodimus and the MP Seekers IMHO. And of course, MP Megatron would have to be the single most frustratingly difficult toy to transform out of every Transformer made!

I know what you mean about the instructions though; I found the instructions weren't that well illustrated or written, which is quite surprising for TakaraTOMY who usually make pretty good instructions that are easy to follow. But even as someone who reads Japanese, I found MP Prowl's instructions to be... "Hasbroesque!"

The tabs can be tricky, but I didn't have any major problems with them. I find them to be fairly intuitive, but yeah, the instructions really don't adequately illustrate or explain what to do w/ them IMO.
