The Malevolent Sentient Poogle Plushie (TCG) is originally a prize that could have been obtained by redeeming base set rare item codes! Now there was a real slim chance of obtaining this prize, but still many tried. You can still obtain these base set rare item codes from various websites like Ebay.
There is also rumors of that you can obtain it by opening Count Von Roo Booster Pack. The pack is about a 4,000,00 item, that when opened rewards you with TCG’s, and you have the chance of winning some high end ones like the MSPP TCG.
The current onsite value in neopoints for the MSPP is around 230,000,000 NP. It is considered to be a ETS item.
By simply having the MSPP TCG in your inventory, you can obtain this cool avatar (sometimes refreshing is required to obtain the MSPP avatar)!
