Aleister appeared on Channel 6 with a piece Lydium 90 in a glass cube and Shredder and Krang saw this on TV and planned to steal it. He forbids his daughter from leaving the embassy unescorted (she is a look-alike of April O'Neil) and she escapes by her discretion. He accused the Turtles of kidnapping her and orders his guards to seize them. He gives the Lydium 90 to Shredder for the release of his daughter but he won't release her (actually April) until he gets where he's going. He reunites with his real daughter and didn't know April was a look-alike and his daughter places Shredder and his 2 mutants under house arrest before they escape. Aleister congratulates the Turtles for winning first prize for most ridiculous costume and gifts them a trophy.
Note: The Lydium 90 sample was unstable and provoked an explosion.</p>
