I'll try another image of Ludicolo (I've been inserting them into Photoshop and overlaying them over the silhouettes for the ones that confuse me) but yeah, I'm starting to agree with you. Nothing else fits.

Here's my list. 50 confused me a lot but I finally put it through some Photoshop filters that upped the contrast and decreased the brightness. Bip bop boop, Linoone's staring me in the face.
