This doesn't really even count as a customization, since all I did was use minimal force to remove the kibble, that can very easily be added back on to allow for Transformation. All you gotta do is pull. I do appreciate HasTak thinking about this, and I truly do think they thought about doing this, for fans that wanted to do this. Some of these parts could have been pinned. The only part that pic hides, is the leg kibble flares, that I think can be pulled off, I just haven't tried since it'll be harder to pull off, if it can. But it definitely doesn't look pinned in there. You can see that kibble in these pics:
Good to know! I'm definitely going to try to get this little guy, even tho I usually don't go for cybertronian alt modes if there's an earth alt mode available.
