This means that your Tokegiss had Pokerus, a rare Pokemon Virus.
If your Pokemon has the virus there will be a sign in its summary. If it has been cured there will be a sign.
When a Pokemon has Pokerus, its EVs gained are doubled. Even if it was cured, the effect stays. A Pokemon with the virus can spread it. To do this, enter a wild battle. Battle a few times(3-5) and your Pokemon will receive Pokerus. To ensure the virus is not cured, keep the Pokemon in your PC.

The sign next to your Nidoqueen means that it is shiny. Shiny Pokemon are very rare. When they are sent out, they sparkle. To find one easily use Chain Fishing or PokeRadar. To breed one easily, use the Masuda Method.
