>>39710865He means the outlines on the textures themselves you mong, not the models. The textures are 100% different, they'd look way beyond ugly if they just used the same ones as they did on the 3DS.
The only obvious example I could point out from that image is the outline of muchlax's belly circle being clearly thicker on the 3DS, since it's lower resolution and would be barely visible if it used the texture that SwSh munchlax uses.
