When Grundel is sulking, dipping his fingers in the water, his brothers inform him that Thumbelina's escaped and taunt him for his failure & he throws them out before storming out of the pond
Mozo: [in a teasing tone] Hey bro...
Grundel: Go away!
Mozo: Pond Doc has said Thumbelina give you the slip, and is gonna marry a fairy prince.
Grundel: [Stands up] What fairy prince?
Mozo: Ho ho ho! You'll not be able to show your ugly face on the stage no more.
Gringo: Everybody laugh at you!
Grundel: Nobody laugh!
[Mozo and Gringo laugh]
Grundel: I said NOBODY laughs!
'[They laugh even harder]
Grundel: I go get Thumbelina and bring her back!
[Mozo & Gringo laugh uncontrollably, and an enraged Grundel throws them up in the air]
Grundel: I marry her!
[Grundel storms off, leaving Mozo and Gringo laughing their heads off]
