Sentret, the Scout Pokémon. Sentret is able to see great distances by rising up on its tail. When it spots an enemy, or any kind of danger, it emits a loud, shrill cry as a warning.

Sentret is Johto’s early starting Normal (rodent-based) Pokemon, much like Rattata, Zigzagoon, Bidoof and Patrat. The wallpaper was slightly challenging to balance because Sentret is so vertical (standing on its tail and all). Sentret kind of looks like a cross between Azumaril and Ursaring, haha.
Stat-wise, since it’s an early Pokemon, its stats are not that great. For some reason though, Sentret can learn Surf.
