Shounen Ashibe (Super Famicom)

Also a big thanks to my lovely boyfriend for finding another one of the old Japanese games I used to play -

For a long time I thought it was Mamegoma but it wasn't! If you get the chance to play it you should, it's just so cute, fun and simple. 

As you can see from the video, you're a seal who goes around collecting things (like apples, chickens, ect.) while avoiding enemies. Some of the items are hidden but if you use your headbutt (and go a bit like Zidane) you can find hidden items behind things or inside places. After you collect everything you go to the goal and move around a map to the next stage.
Definitely one of my favourite games and hope to get to watch the anime sometime too.
