I did not think anything special. At the moment I just thought Seismitoad was cool and I did not pay Palpitoad much attention. But later on when Ash catched it in the anime I watched it more closely and I started to love it! It was a certain picture...
I shall try and add it to Club Pictures.
OK I added it to Group Photos. It is the picture on Palpitoad standing on a flower on the water. Picture is from the anime.
To be honest, at first I didn't like Palpitoad, or many other 5th generation Pokemon, back when he got introduced I only liked cat Pokemon and never imagined myself liking any other kind.
With pass of time, I learned to like many Pokemon, including Palpitoad, from the 5th generation, now the 5th generation has more Pokemon I like than all others.
sum it up: Didn't liked it at first, pass of time I learned to love Palpitoad.
I didn't pay much attention at first, and only used it because I needed a water type that seemed good. It proved quite useful, especially fully evolved. I'm sad to say it doesn't get much action anymore even since being overshadowed by some of my other Pokémon.
