Whaaaaat?! I've never heard of those! oO But I just checked, and wow! Why would they bring in Indian elephants and tell you to give up? O_O
I really love your response, LuminousWarrior! =D I'm glad to see this topic gets such great feedback! ^-^
AHEM! Right! I should post some entries as well.
*sweat*
Mew 
in
FireRed:
"A Pokémon of South America that was thought to have been extinct. It is very intelligent and learns any move."
South America, huh? Not like a tropical region or an unknown location? No, straight up South America! oO
There are so many on the leek stalk of
Farfetch'd 
, it might as well glitch that brain of it. Since there are so many to list, I might as well show a link to all of them instead:

If you're interested, I've used Bulbapedia's Farfetch'd picture and edited it to showcase a lot of stuff that I think is wrong with it. =P
Okay, last one I'll post for now...
Regice 
in
Pokémon Sapphire:
"Regice cloaks itself with frigid air of negative 328 degrees F. Things will freeze solid just by going near this Pokémon. Its icy body is so cold, it will not melt even if it is immersed in magma."
the air around Regice: -328° F / -200° C
Liquid Nitrogen: -321° F / -196° C
Liquid Oxygen: -298° F / -183° C
Liquid Air: -318° F / -195° C
(http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/liqair.html)
So it seems that
Regice is surrounded by liquid air, wow! I didn't even know that the air we breathe can turn into liquid, but there you go! So... does that mean it can use Surf on land? Seeing how it turns all the air around it into a liquid? Call it...
Subsurfo /
Sub-surf-o! ^^
(bad pun on sub-zero and Surf)
