Skeetendo

I'm having an issue when creating a new person event with the overworld sprite of a rocket. I give it the sprite number every rocket has (0x35) but the sprite shows as hiro's sprite. I suppose it has to do with the fact that not every sprite can be shown with every tileset or something like that but I have no idea what I should do to make a person have the sprite of a rocket in route 39. (I'm also having the same problem with raikou's sprite in cianwood sprite.)

That's the definition of the person events in hex (two rockets):

35 24 0C 07 00 FF FF 00 00 00 74 57 07
35 24 0D 07 00 FF FF 00 00 00 74 57 07

0x00 0x74 is the pointer to a simple script that just shows text and works fine; the problem I have is just the sprite.

Thanks in advance.
