I have one of those too, but mine dosen't look like a penguin. Mine is egg-shaped, and blue and green. Spongebob is on mine also, as well as all the other characters you listed. It is pretty bad, and the reset button is also on the front, so easy to push by mistake. The only good thing about...
My best deal was my green Santaclautch in got in 2004. I got it at Goodwill for 20 or 25 dollars (been so long I forgot). Brand new in box, just needed new batteries, works fine.
I still run my greyscale tamas every now and then when I choose to run one. Also my Uratamas, and Akais. I'll choose to run those over any of my color ones.
